Anti-light-leakage and high-contrast liquid crystal display structure and display method thereof

Abstract

The invention provides an anti-light-leakage and high-contrast liquid crystal display structure and display method thereof. The anti-light-leakage and high-contrast liquid crystal display structure comprises an upper polarizer, a lower polarizer and a liquid crystal layer clamped between the upper polarizer and the lower polarizer. A plurality of glass beads are placed on the liquid crystal layer. The glass beads are lighttight. The glass beads bear the upper polarizer and the lower polarizer and stops light from leaking outwardly at the positions of the glass beads. The invention further provides a display method using the display structure. Due to the fact that the glass beads are black and lighttight, when people watch a screen, white light generates linear amplification at nerve cells, the edges of the black points are dimmed by the surrounding white light, compared with white light-permeable glass beads, the displayed black points look smaller by visual effects in coordination with the black glass beads, overall definition is enhanced, and speckles are few.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a high-contrast liquid crystal display structure. Background technique [0002] Since the liquid crystal molecules themselves cannot emit light, if the picture is to appear, the LCD screen needs a special light source to provide light, and then the liquid crystal molecules are deflected to produce different colors, and the backlight plays the role of providing light energy. . After the LED emits light, the light is distributed everywhere through the light guide plate, and the direction of all the light is concentrated towards the liquid crystal molecules through the reflector on the back. Finally, the light is distributed evenly through the prism sheet and the diffuser plate, so as to avoid the situation where the central brightness is too high and the surrounding brightness is too low. [0003] In the principle of liquid crystal display, the upper and lower laye...

AI Technical Summary

Problems solved by technology

Since there is no liquid crystal in the space occupied by the glass beads, the polarization direction of the light cannot be changed, and the glass beads are transparent, so the light will pass through the upper polarizer.

As a result, in some pictures with a black background, the place where the glass beads are placed on the screen shows white spots

From the customer's point of view, due to the position of the glass beads, there will be this light...
