Liquid crystal display

Abstract

An LCD display includes: backlight, the first polarizer that is installed at the top backlight, the first transparent substrate that is installed at the top of the first polarizer, collector array that is installed at the surface of the first transparent substrate polarizer and adjacent to the first polarizer, and each collector array includes: a first refractive block and a number of second high refractive blocks that is located on two sides of the first block, and the two second blocks in the symmetry position have the same width. There is a low refractive block between one first and one second high refractive block, and the width of the first is greater than the second. The second transparent substrate is installed on the top of the first one and has the transparent area that is allocated corresponding to collector array. The LCD layer is located between the first and second transparent substrate. A second polarizer is installed at the top of the second transparent substrate. The invention can effectively lower the leaky light phenomenon when dark.

Description

technical field [0001] The present invention relates to a liquid crystal display, and in particular to a high-brightness liquid crystal display. Background technique [0002] In recent years, optoelectronic-related technologies have been continuously introduced, coupled with the arrival of the digital age, which has further promoted the vigorous development of the liquid crystal display market. Liquid Crystal Display (LCD) has the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide application range, so it is widely used in portable TVs, mobile phones, notebooks, etc. Consumer electronics or computer products such as computers and desktop monitors are gradually replacing cathode ray tubes (Cathode Ray Tube; CRT) to become the mainstream of monitors. [0003] In view of the fact that the liquid crystal itself does not emit light, it is necessary to use a backlight module to supply the light source in order to achieve ...

Problems solved by technology

However, the biggest difficulty of this method is that since the size of the microlens is below the micron level, and its surface structure is a curved surface structure, it is not easy to control in production.

Furthermore, due to the limited size and structure of the microlens, it is no longer possible to increase the curvature of the curved surface structure of the microlens to further enhance the brightness of the liquid crystal display.
