Embodiment 1

[0044] Specifically, the embodiment of a liquid crystal screen provided in the technical solution of the present invention is as follows Figure 4 to Figure 6 shown. The liquid crystal screen in this embodiment is a liquid crystal touch panel as mentioned above. refer to Figure 4 As shown, in the technical solution of this embodiment, the upper-line polarizer 220 is moved to the outermost surface of the liquid crystal touch panel, and an upper λ / 4 wave plate 204 is added between the upper transparent substrate 200 and the upper-line polarizer 220 A lower λ / 4 wave plate 104 and a lower line polarizer 110 are added outside the lower transparent substrate 100 . That is, on the upper surface of the liquid crystal layer, starting from the outermost layer, there are an upper linear polarizer 220 and an upper λ / 4 wave plate 204 in sequence. That is, on the lower surface of the liquid crystal layer, starting from the outermost layer, there are an upper linear polarizer 110 and a l...

Embodiment 2

[0051] An embodiment of the present invention is specifically as Figure 7 to Figure 10 shown. refer to Figure 7 As shown, in the technical solution of this embodiment, the upper λ / 2 wave plate 215 located between the upper line polarizer 220 and the upper λ / 4 wave plate 204 is added on the basis of the first embodiment, and the lower line polarizer The lower λ / 2 wave plate 115 between the plate 110 and the lower λ / 4 wave plate 104. That is, on the upper surface of the liquid crystal layer, starting from the outermost layer, there are an upper linear polarizer 220 , an upper λ / 2 wave plate 215 and an upper λ / 4 wave plate 204 in sequence. That is, on the lower surface of the liquid crystal layer, from the outside to the inside, there are an upper linear polarizer 110 , a lower λ / 2 wave plate 115 and a lower λ / 4 wave plate 104 .

[0052] In this embodiment, the linear polarizer is marked as PL, the transmission axis direction of the linear polarizer is marked as p, the λ / 4 w...

Embodiment 3

[0063] An embodiment of the present invention is specifically as Figure 13 to Figure 14 As shown, on the basis of the second embodiment, an additional λ / 2 wave plate 225 is added between the upper line polarizer 220 and the λ / 4 wave plate 204, and an additional piece of λ / 2 wave plate 225 is added between the lower line polarizer 110 and the lower λ / 4 wave plate. An additional λ / 2 wave plate 125 is added between the wave plates 104 . That is, on the upper surface of the liquid crystal layer, starting from the outermost layer, there are an upper linear polarizer 220 , λ / 2 wave plates 215 and 225 , and a λ / 4 wave plate 204 . That is, on the lower surface of the liquid crystal layer, from the outside to the inside, there are an upper linear polarizer 110 , a λ / 2 wave plate 115 and 125 , and a λ / 4 wave plate 104 . The newly added λ / 2 can increase the wavelength of new circularly polarized light, so that the wavelength band of the light wave passing through the liquid crystal scr...

Abstract

The invention discloses a liquid crystal display, which comprises a liquid crystal panel, wherein the liquid crystal panel is provided with an upper baseplate, a lower baseplate and a liquid crystal layer positioned between the upper baseplate and the lower baseplate; one side, closely adjacent to the liquid crystal layer, of the upper baseplate or the lower baseplate is the inner side, and one side relative to the liquid crystal layer is the outer side; metal electrodes are arranged on the inner side of the lower baseplate; and a layer of linear polarizer, m layer / layers of Lambda / 2 wave plate / wave plates and one layer of Lambda / 4 wave plate, and the m is equal to or greater than zero. The technical scheme of the invention can shield the reflected light of metal wires in the liquid crystal panel, and improves the display effect of the liquid crystal display.

Description

technical field [0001] The invention relates to the field of liquid crystal display screens, in particular to a liquid crystal screen. Background technique [0002] Embedded touch technology is a technology that combines a touch panel and a liquid crystal panel. The touch technology of the touch panel can be capacitive touch, resistive touch or infrared touch, etc., and the structure of the liquid crystal panel is also It can be a common TN (Twisted Nematic liquid crystal, twisted nematic liquid crystal) mode, an IPS (InPlane Switching liquid crystal, in-plane switching liquid crystal) mode or an FFS (Fringe Field Switching liquid crystal, fringe field switching liquid crystal) mode, etc. At present, the main development direction of embedded touch technology includes In-Cell (inside liquid crystal) embedded touch display device, which is to embed touch sensors into liquid crystal pixels. It can complete the manufacturing technology of the touch sensing element in the TFTLC...
