Embodiment Construction
[0024] See figure 1 , Which is a schematic cross-sectional view of the first preferred embodiment of the eye protection grating for the liquid crystal display screen of the present invention. The eye protection grating of the liquid crystal display screen of the first preferred embodiment mainly includes: a transparent substrate 10, a transparent packaging plate 20, a liquid crystal material 30 for changing the polarization state of the emitted light, a transparent layer 40, and a liquid crystal alignment material 50; The layer 40 is a linear stripe distributed longitudinally or laterally on the transparent substrate 10, and grooves are arranged between adjacent linear stripes. The widths of the linear stripes and grooves are equal to the horizontal width or the vertical length of the pixels of the liquid crystal display. The liquid crystal alignment material 50 is arranged at the bottom of the groove, the liquid crystal material 30 is filled in the groove and aligned via the li...

Abstract
The invention relates to a liquid crystal display screen eye-protective grating. The liquid crystal display screen eye-protective grating comprises a transparent substrate, a transparent packaging board, a liquid crystal material used for changing an emergent light polarization state, a transparent layer and a liquid crystal alignment material; the transparent layer is linear fringes longitudinally or transversely distributed on the transparent substrate, grooves are formed between the adjacent linear fringes, the width of the linear fringes and grooves is the same as the transverse width or longitudinal length of liquid crystal display screen pixels, the liquid crystal alignment material is arranged at the bottom of each groove, the grooves are filled with the liquid crystal material which is subjected to alignment through the liquid crystal alignment material, and the transparent packaging board and the transparent substrate are packaged together in an up-down mode. The invention further provides another liquid crystal display screen eye-protective grating. The liquid crystal display screen eye-protective grating can change polarized light output by a liquid crystal displayer into natural light and has the advantages of being simple in structure and low in cost, and natural light subjected to blending can relieve visual fatigue caused by watching the liquid crystal display screen for a long time.
Description
Technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a liquid crystal display eye protection grating. Background technique [0002] Liquid crystal displays have excellent performance, good mass production characteristics, high automation, low raw material costs, and broad development space. They will quickly become mainstream products in the new century and a bright spot for global economic growth in the 21st century. Most of the liquid crystal displays are backlit liquid crystal displays, which are composed of a liquid crystal display panel and a backlight module. The light emitted by a general liquid crystal display panel is linearly polarized light, which is likely to cause visual fatigue. [0003] In order to alleviate the visual fatigue of watching the LCD screen for a long time, the known eye protection technology is the CPLP (Circular Polarized Screen) health eye protection technology developed by Huaxing Optoelectronics.
