Embodiment Construction

[0038] Such as figure 1 As shown, a liquid crystal display grayscale raising device based on a laminated liquid crystal screen includes a video source 1, an N-layer laminated liquid crystal screen 2, a backlight 3 and an electronic device 4 for driving a laminated liquid crystal screen. The N-layer laminated liquid crystal display The first-layer liquid crystal screen 21 of the screen 2 is bonded and fixedly connected to the backlight source 3. The video source 1 sends video images to the electronic device 4 driving the laminated liquid crystal screen, and the electronic device 4 driving the laminated liquid crystal screen receives the video image and The video image is decoded to obtain a computable image data format, and the sub-image division algorithm is used to divide the high-gray image into N sub-images, and the N sub-images are sent to the N-layer laminated liquid crystal screen 2, and the N-layer laminated liquid crystal Screen 2 synchronously displays sub-images of c...

Abstract

The invention discloses a display gray scale improvement system based on a laminated liquid crystal display, comprising: a laminated liquid crystal display device, a sub-image division algorithm, and a synchronous driving electronic device for the laminated liquid crystal display. The method includes: closely laminating N layers of ordinary 8-bit liquid crystal screens together, using a sub-image division algorithm to divide the high-gray-scale image into N sub-images, and each layer of liquid crystal screens displays the sub-images of the corresponding layer, and all sub-images The image is displayed synchronously, which can realize the display of high-gray-scale images, which improves the display gray-scale of ordinary 8bis liquid crystal displays, and improves the contrast of image display.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal display grayscale raising device based on a laminated liquid crystal screen. Background technique [0002] At the end of the 19th century, Austrian botanists discovered liquid crystals, that is, liquid crystals: a substance that has both the fluidity of a liquid and certain alignment characteristics similar to crystals. Under the action of an electric field, the arrangement of liquid crystal molecules will change, thereby affecting its optical properties. This phenomenon is called the electro-optic effect. Utilizing the electro-optic effect of liquid crystals, British scientists manufactured the first liquid crystal display, or LCD, in the last century. [0003] Compared with the traditional CRT, LCD is not only small in size, thin in thickness, light in weight, low in energy consumption, low in working voltage and has no radiation, no flicker, a...
