Abstract

PURPOSE:To obtain synchronizingly colored to a field sequential monocolor picture by switching the picture signal to the red, blue and green field sequential system signals at each field and utilizing a ferrodielectric high elastic solid-state electron hue modulating element arranged in front of the picture. CONSTITUTION:Red, blue and green video signals (R, G, B) are inputted serially to the next synchronizing circuit 11, fed splittingly with synchronism to an X axis driver and a y axis driver of a single color liquid crystal wrist television screen 12 for displaying picture. This picture is the R, G, B single color picture, but R, G, B colors of an electronic color filter are applied in synchronizing with an electronic color filter 14. The signal is switched respectively to single color in the three primary colors by a switching circuit 10 and the timing signal at switching is inputted to an electronic color filter driver 13 to form an inputted pulse code and a pulse voltage. The pulse is impressed to A-A', B-B' and the color of the filter is selected in synchronizing with the color video signal to form the color picture of field sequential type.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color TV screen with a liquid crystal display element, in particular, a monochromatic liquid crystal six-arm television screen with a strong elastic solid ridge hue modulation element in front of the screen. There is something wrong with the LCD color arm TV reception area, which was rebuilt and the field was changed to a new type.

The conventional 7-night In TV has not been released in a single color, and it is said that it is extremely difficult to display the product in full color. However, most of the TV radio waves that are being broadcast and transmitted are in color, and monochromatic TVs are not enough, and the city and government are strongly requesting colorization.

The present invention was developed recently, and is designed to be compact and capable of color printing. Improved the color, and replaced the qJ9 with the three primary colors of red and -61 green fields for each image field containing the color Gogo, and the same 1 temple (with 1 elephant facing forward). Due to the placed ``Ko-Yuu'' Shinkyo Danchu Group'' Nozomi Hue F-tone element,
The field is a color image synchronized with a monochromatic 1III image, which composes a liquid crystal color TV. FIG. 41 is a diagram showing the principle of the present invention. 1 is a field Junten method single-color LCD arm TV that is a complete improvement over the conventional early color arm TV. 2.
This is an electronic hue modulator (electronic color filter) placed in front of the TV image. To explain the structure of this electronic color filter, 6 is a polarizer, and the circular wave light from the TV 1 is transmitted through the polarizer 5? ”
↓ and then the straight line 1 and then the next birefringent body 4
4].

Birefringence (11 bodies 4 is 1+lJ, then a crystal plate is used.

5 and 6 are gadolinium molybdate 1 od2 (M
oD4 > s ] and other birefringent crystals. 7 is an analyzer, and electrode A is located at the upper and lower ends of the birefringent crystals 5 and 6 [m].

An image in which each of the three primary colors of light is sequentially added to A', B, and B' using a specific component of only the next phase difference, which is modulated by the vise X and 'intraocular pressure pulse gold stamp υat2' of the main TV 1. [7] will be placed in observation number 8.

A detailed explanation of the operation of electronic color filters.

The phase point of the birefringent body 4 and the birefringent crystallizer 5.6 is J(/'
Ao = 3/2 to 5/2 Tonai and Azaya 7) > (The color will turn dark. Here, R is the phase difference, λ. It is the wavelength of the color. The phase light of the birefringent plate 4 R, phase difference of multi-layer 17T crystal plate 5.6 respectively) (G, .RGll
Then, the overall phase is ! i;R is R: Rof RG
, Sat i (G, 1 and 9, RG, .

f"II is the electrode A-A', B-B' at the two lower ends.
By applying a voltage pulse for about 171,000 seconds, the three primary colors appear.
. The combination of the signs of the pulses marked on "l+RGli" represents four colors, but the five primary colors red, -■, and green can be expressed as follows. Hello.

Red: Ro-RG, -, R(),.

t: R(, + Go, -RG,.

Green: Rof Ro, -4-Re, 1 Pulses containing this entire code are supplied from the arm TV.

FIG. 2 shows an embodiment for converting a monochrome image on a television into a color image, and will be explained in detail in the following. Processed by the television circuit 9, audio number 1, synchronization signal, color? A video signal containing the image is created.

This tsuchi audio No. 1H will be supplied to headphones etc. The color video signal that received the 100th synchronization signal enters the switching circuit 10. The explanation is given in NTSO Manshiki, but other methods are also available, and all 7JLI books are the same.
l. In the switching circuit 10, the three primary colors red, l\, and green fee L do l1ll'U' are praised by everyone, 1
Field 7g becomes the video signal of red, spine, and edge. Therefore, an image with 60 fields per second is 10 fields per second.
Since 121J is replaced by 121J, 20 sheets of each of the three primary colors are swiped in a total of 6o fields in one second. 11
[-Since each field has a color, the color flickers (R: Yes, it should be, but the remaining 1 field of the eye is very noticeable (・1 field. The time of 1 field is 1/60 second, which is 16.7 milliJ seconds each.There is a Mobarth who is interested in the above-mentioned electronic color filter.
1. /1000 seconds, so the effect is fully demonstrated.

The red, evening, and green video signals (R, B, G) sequentially enter the next synchronization circuit 11 and are synchronized and divided into the Xllil driver and Yllil driver of the monochrome LCD arm TV screen i12. is supplied and an image is displayed. This image is a monochromatic double-sided image of m, , s, and G, but in synchronization with the electronic color filter 14, which will be explained briefly, the colors of f(, B, and G of the electronic color filter are Especially 14). As a result, to the human eye, the six snakes became a full-color painter. At the same time as the switching circuit 10 switches each of the six quintillion colors to the first single color, this switching timing No. 14 is input to the electronic color filter driver 16 and the above-mentioned ±RG, , 1
(0, , J addition) No. 2 and a pulse voltage are created. -A' to the pulse voltage.

The color of the filter is selected by applying the same signal as the color video signal Jυ to B-B', and the field sequential type color 1
It becomes a Jjil image.

'The area of the electronic color filter is
ii
Ame in Kakuzentai. A 1M photon, a birefringent material, two birefringent crystal plates, and an analyzer are stacked on top of each other. Therefore, we decided to create an LCD color arm TV that is about one size smaller than the leg TVs currently on the market.

As explained above, according to the present invention, it is possible to provide all liquid crystal color televisions on the market that have cheap water, and the effects thereof are extremely large.
