ãããã[0003] In a general conventional optical transmission device, an RGB video signal is converted into a digital video signal by an AD converter. The converted digital video signal is subjected to data compression by an MPEG encoder to become an MPEG signal. The MPEG signal is modulated by a modulation circuit and applied to a light emitting diode. Light emitted from the light emitting diode is transmitted through a space or an optical fiber and received by the photodiode.

è¦ãããã[0004] Spatial light transmission, which radiates light into space and transmits it, requires a high-power light emitting diode. Further, a photodiode having a high sensitivity is required. However, these devices have a low response speed and cannot secure a sufficient transmission bandwidth. Therefore, it is necessary to compress the video signal data by the MPEG encoder so that the data rate is equal to or less than the bandwidth of the optical transmission.

è¦ãªããThe rising edge pulse waveform 49 of the rising edge signal is the signal waveform after being delayed by the delay circuit 36c. These are combined by the SR-FF 37, and a reproduced waveform 39 is obtained at the output. The reason why the output of the edge detection circuit 35c is delayed by the delay circuit 36d is to match the phase with the rising edge pulse waveform 49 of the rising edge signal, and is not necessary if the pulse width of the falling edge waveform 48 is sufficiently narrow.

As another example, a differentiating circuit using a resistor and a capacitor may be used. At this stage, the fluctuation of the average voltage generated due to the limitation of the response speed of the light emitting diode 32 and the photodiode 33 is almost removed, and the edge information which is less susceptible to the deterioration due to the response speed is extracted from the deteriorated waveform.

Also, since both the upper 4 bits and the lower 4 bits are temporarily stored in the frame memory 15, it is possible to perform a frame rate conversion for changing the frame rates of the input video signal and the output video signal. If such a function is not required, the upper 4-bit frame memory can be omitted.

The lower 4 bits are stored in the frame memory 15b. Upper 4 bits and lower 4 bits of data are read at a data rate of 2: 1. At this stage, the lower 4 bits of data are thinned out, and the data to be transmitted is reduced. Although details will be described later, the frame rate of the lower 4 bits is half that of the upper 4 bits. The encoder 16 encodes the data into serial data suitable for spatial light transmission.

The light is amplified by the driver 31 and emitted as infrared light 19 from the LED 32. A quantization error occurs due to AD conversion of an analog video signal. In the present invention, video data and the like are divided into bits and transmitted at different rates. Then, a quantization error is noticeable during reproduction. If converted into a gray code and transmitted, the quantization error is dispersed, and the quantization error can be prevented from being noticeable during reproduction.

FIG. 23 shows an optical transmission format of light emission according to the present invention. FIG. 23 shows an example of the transmission format according to the third aspect. According to the present invention, one data is transmitted as a 1024-bit packet as a delimiter. The packet size may be any multiple of 1024. However, when the size of one packet becomes longer, the period in which an equalizer described later appears becomes longer, and the period tends to become unstable. Therefore, the appropriate size of the packet is 1024 bits or 2048 bits. The video data is transmitted by transmitting the packet continuously or intermittently.

That is, the receiving side is asynchronous with the transmitting side. Therefore, it is necessary for the receiving side to independently generate a synchronization signal (clock). The clock needs to be stabilized during the marker period. Therefore, the marker string needs to have a sufficient length compared to the length of the data block.

Therefore, the peak detection circuit 91 is provided with a resistor 942 to have a constant time constant. With such a circuit configuration, the value of the reference voltage always becomes an appropriate value according to the transmission state.

æ´ãããFIG. 95 is an explanatory diagram of the operation of the circuit. â1
When an equalizer bit string of "010 ... 10" is input, edge data is extracted from the input signal.
Here, if only the rising edge is used for ease of explanation, the buffer 943a charges the hold capacitor 941 with the edge data, and the hold capacitor voltage gradually increases as shown in the figure. If there are 14 equalizer bits as in the present invention, the rising edge appears seven times. The voltage of the hold capacitor is maintained at the target voltage (reference voltage 1) by these seven charges. A part of the held voltage is gradually discharged by the discharge resistor 942, so that the optimum target voltage for the transmission state is set even if the state of the transmission line changes. With this voltage, the gain of the variable amplifier 34 is adjusted via the buffer 943b.

The decoder circuit 25 checks every packet or every few packets whether an error check bit string is described in the control code. If the error confirmation bit string cannot be confirmed (if different), it is determined that there is an obstacle in the transmission path and the infrared rays 19 are shielded.
In this case, if the decoding circuit 25 does not write the data of the data block into the memory 15, the data in the memory 15 does not change. Therefore, the data synthesizing circuit 26 converts the data into image data using the previous data. Therefore, nobody occurs on the display screen 291 alone. Naturally, the image on the display screen 291 remains stopped because it was previously received data. However, no image is generated.

The arrangement of the object detection sensor 20b near the light emitting element 32 and the object detection sensor 20a near the light emitting element 32 is also exemplified.
The object detection sensor is sold by Keyence Corporation.
It receives infrared rays and the like, and the light emitting element 3
2. It is detected whether there is any obstacle on the front surface of the photodiode 33 or the like. When detecting an obstacle, the decoder circuit 25 does not write the received data to the memory 15.
In addition, the mode is entered into a marker bit detection mode and a start bit detection mode. By controlling in this way, no image is lost.

A code for performing scrambling is written in the scramble bit string as shown in FIG. Decoder circuit 2
Reference numeral 5 indicates that if a scramble bit string is described, one bit of data of the data block is deleted or inserted for each packet or every several packets. Then, image disorder occurs. If all the data is shifted from the packet including the start bit, the contents of the image become completely random. However, if the data of only a few packets of one screen is shifted, it is possible to easily recognize the contents of the image or to make the image (scramble) very difficult to see.

5) and the reading side (data synthesizing circuit 26) are not synchronized in the VD cycle, and if the image changes in the middle of the screen,
Image breaks (two images with different fields appear)
This is because there is a line. Therefore, when reading is performed early on the reading side or when the writing side is slow (or fast), data writing to the memory 15 is stopped for synchronization. Alternatively, the reading of data from the memory 15 is stopped until the reading side receives the next VD.

It is preferable that the shape of 72 is not a square or a circle but a rectangle or an ellipse. The directivity between the left and right and up and down is changed, and the transmission / reception state can be improved. In general, it is better to broaden the directivity of light emitted from a light emitting element to the left and right. The vertical direction may be relatively narrow. This is because the receiving unit and the transmitting unit are often used by being arranged at substantially the same horizontal position, and the vertical displacement can be easily adjusted by the operator. In order to widen the left and right directivity, there is a method of changing the luminous body image by the diffusion plate 372, but there is also a configuration in which the condensing lens 356 is formed in the shape of a convex lens. Further, it may have an aspherical shape.

In field 2, data 2-1 is written in the two pixel rows in which data 1-1 has been written first, and
Data 2-2 is sequentially written in the pixel row. That is, the same image data is written every two pixel rows in one field.

Since the images 1-1 and 2-1 are the same image, it tends to be considered that the resolution is not improved. However, in reality, it can be displayed with a resolution of 480 horizontal pixel rows or more. This is because the signal captured by the broadcast camera has a wide band. When capturing 480P (progressive) video, the video signal taken in from the problem of aliasing frequency is passed through a filter to limit the band. However, an ideal steep band filter cannot be realized. For this reason, a video signal is formed in a wide band in spite of the aliasing frequency, and this video signal is transmitted as a broadcast wave. Therefore, the received radio wave receives a wideband video signal having a band of 480P or more.

ãããThe reason for making the pixels rough at the edge area of the screen and making the pixels fine at the center as described above is that the human eye has a high resolution at the center of the screen, and the peripheral part of the screen is hardly seen. This is because there is no practical problem even if the resolution is low. Note that, in each drawing, a TFT 475 or the like is illustrated only for a part of pixels, but at least one or more switching elements such as TFTs are formed or arranged in each pixel.

As the polymer, a photo-curing type resin is used in view of easiness of a manufacturing process, separation from a liquid crystal phase, and the like. As a specific example, an ultraviolet curable acrylic resin is exemplified, and a resin containing an acrylic monomer or acrylic oligomer which is polymerized and cured by irradiation with ultraviolet light is particularly preferable. Above all, a photocurable acrylic resin having a fluorine group is preferable because a PD liquid crystal layer 591 having good scattering characteristics can be manufactured and a change with time hardly occurs.

ããIn the PD liquid crystal, it is desirable to form a portion (region) in which each pixel has a different average particle diameter of a liquid crystal droplet or a different average pore diameter of a polymer network. There are two or more different areas. The TV (scattering state-applied voltage) characteristic is changed by changing the average particle diameter and the like.
That is, when a voltage is applied to the pixel electrode, the region having the first average particle diameter is first in the transmission state, and then the region having the second average particle diameter is in the transmission state. Therefore, the viewing angle is widened.

ããAs shown in FIG. 60, it is effective to form an insulating film 604 between the pixel electrode 561a and the liquid crystal layer 591a and between the liquid crystal layer 591a and the counter electrode 603a.

ããFurther, the formation of the insulating film 604 also has the effect of making the pore diameter (hole diameter) of the polymer network of the liquid crystal layer 591 or the particle diameter of the water-droplet liquid crystal almost uniform. This is presumably because even if an organic residue is present on the counter electrode 603a and the pixel electrode 561a, the organic residue is covered with the insulating film. The coating effect is better with PVA than with polyimide. This is probably because PVA has higher wettability than polyimide. However, according to the results of reliability (light resistance, heat resistance, etc.) tests performed on various types of insulating films formed on the panel, the display panel formed with polyimide used for the alignment film of the TN liquid crystal shows almost no change with time. Good. PVA tends to have a lower retention and the like.

In a CRT, the display luminance at the time of a white raster is different from the display luminance of a portion where a very small area is displayed in white by one digit or more. The display luminance at a place where the very small area is displayed in white is called peak luminance.

Since hydrogen has a low specific gravity, windage loss caused by rotation of the rotary filter 654 can be reduced. Also, the heat radiation effect is high. However, hydrogen can explode when mixed with oxygen. Therefore, a pressure / purity sensor 661 for measuring the pressure and luminance of hydrogen is attached to a part of the housing 664. The pressure / purity sensor 661 measures the pressure and / or purity of hydrogen in the housing, and issues a signal when the concentration of hydrogen or the like falls below a certain value. In response to this signal, the indicator lamp âCheck hydrogen concentrationâ is turned on, and the lamp 651 is checked.

The AIR coat has a three-layer structure or a two-layer structure. In the case of three layers, it is used to prevent reflection in a wide visible light wavelength band, and is called a multi-coat. In the case of two layers, it is used to prevent reflection in a specific visible light wavelength band,
This is called a V coat. The multi-coat and the V-coat are properly used depending on the purpose of the liquid crystal display panel.

ããIt is preferable that the gate driver circuit 461 and the source driver circuit 462 be manufactured using a high-temperature polysilicon technique or a low-temperature polysilicon technique from the viewpoint of cost reduction. When a driver circuit is manufactured by these techniques, a driver 461 (46) is formed as shown in FIG.
2) No liquid crystal layer 591 is formed or arranged on the circuit. This is because if the liquid crystal layer 591 is formed, the inverter circuit and the power supply wiring forming the driver via the liquid crystal layer 591 are electromagnetically or electrostatically coupled, and malfunction.

When the liquid crystal display panel of the present invention is used as a light valve or the like of a projection display device, the present invention is not limited to this. The absorbing material of the liquid crystal display panel that modulates the R light may absorb the R light. Therefore, a natural resin can be dyed using a dye, or a material in which the dye is dispersed in a synthetic resin can be used. For example, an appropriate one of an azo dye, an anthraquinone dye, a phthalocyanine dye, a triphenylmethane dye, or the like, or a combination of two or more thereof may be used. In particular, it is preferable to use those having a complementary color relationship. For example, when the incident light is blue, the absorbing material is colored yellow. Further, it may be formed of a tungsten silicide film or a metal thin film of Al, Cu, Ag, Cr or the like.

However, if it is used for an illumination system, there is no problem at all due to the effect of color misregistration. Therefore, it should be formed of a polycarbonate resin that can make use of the characteristic of high refractive index. Since the refractive index is high, the curvature of the paraboloid can be reduced, and the size can be reduced.

ãã¦æå¹ã§ãããThe pixel structure may be either a common electrode type or a pre-stage gate electrode type. Alternatively, a stripe-shaped electrode made of ITO may be formed on the array substrate 601 along the pixel row (horizontal direction), and a storage capacitor may be formed between the pixel electrode 561 and the stripe-shaped electrode. By forming the storage capacitor in this manner, a capacitor is formed in parallel with the liquid crystal layer 591. As a result, the voltage holding ratio of the pixel can be improved. The TFT 416 formed of low-temperature polysilicon, high-temperature polysilicon, or the like has a large off-state current.
Therefore, it is extremely effective to form this striped electrode.
