Problems solved by technology

When the squint angle is 0 degrees, the display brightness percentage is 1, that is, the line of sight is perpendicular to the screen, and the screen brightness is the highest at this time; when the squint angle is within -35 degrees to 35 degrees (the viewing angle range of the screen is -50 degrees to 50 degrees), the percentage of display brightness decreases rapidly, that is, the brightness of the screen drops rapidly, which fails to achieve the purpose of sharing information

[0032] figure 2 It is a structural schematic diagram of the liquid crystal display of the first embodiment of the present invention. Such as figure 2 As shown, the liquid crystal display 100 includes a display panel 10 and a backlight module 20 . The display panel 10 is disposed above the backlight module 20 . The backlight module 20 is used to provide a light source for the display panel 10 , specifically, the backlight module 20 includes a backplane, a light source, a reflection sheet, a light guide plate, a diffusion sheet, and the like. In this embodiment, the display panel 10 includes a display surface and a light incident surface oppositely arranged, the display surface of the display panel 10 is used for displaying images, and the light incident surface of the display panel 10 is used for receiving the backlight emitted by the backlight module 20 .

[0033] Such as figure 2 As shown, the display panel 10 includes a first substrate 11, a second substrate 12, a liq...

[0045] Figure 5 is a schematic structural diagram of the diffusion membrane of the second embodiment of the present invention. Such as Figure 5 As shown, the structure of the diffusion film 15b of this embodiment is substantially the same as that of the diffusion film 15a of the first embodiment, except that the particle diameters of the diffusion particles 156b of the diffusion film 15b are different.

[0046] The diffusion film 15b is used to diffuse the light emitted from the display panel 10, so that when the liquid crystal display is switched to a wide viewing angle mode, the naked eye squints from one side of the display panel 10 to watch the other side of the display panel 10, and the angle of the squint increases continuously. Large, there will be no problem that the brightness on the other side of the display panel 10 drops rapidly, so as to achieve the purpose of sharing information. The diffusion film 15b is provided with a plurality of diffusion particles 156b ...

[0054] Figure 6 It is a structural schematic diagram of the liquid crystal display of the third embodiment of the present invention. Such as Figure 6 As shown, the structure of the liquid crystal display 100 of this embodiment is substantially the same as that of the liquid crystal display 100 of the first embodiment, except that the position of the diffusion film 15a is different.

[0055] Specifically, such as Figure 6 As shown, the display panel 10' includes a first substrate 11, a second substrate 12, a liquid crystal layer 13, an upper polarizer 14a, a lower polarizer 14b and a diffusion film 15a. The first substrate 11 and the second substrate 12 are arranged oppositely, the liquid crystal layer 13 is arranged between the first substrate 11 and the second substrate 12; the upper polarizer 14a is located above the lower polarizer 14b, and the upper polarizer 14a is arranged on the display panel 10 The display surface of the lower polarizer 14b is the incident surfac...

Abstract

The invention relates to a liquid crystal displayer. The liquid crystal displayer comprises a display panel, the display panel is provided with a diffusion film, and the diffusion film comprises an intermediate zone, a first smooth zone and a second smooth zone; the intermediate zone is located between the first smooth zone and the second smooth zone, the center of the intermediate zone overlaps with an intersection point of diagonals of the display panel, and the haze degree of the first smooth zone and second smooth zone gradually increases in the direction away from the intermediate zone. The liquid crystal displayer can meet TCO5.0 measurement standards, and when a person squints a screen of the liquid crystal displayer, the problem that the brightness of the screen rapidly decreases cannot occur; the purpose of sharing information is achieved.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a liquid crystal display. Background technique [0002] Liquid Crystal Display (LCD) not only has the characteristics of being light, thin, and small, but also has the advantages of low power consumption, no radiation, and relatively low manufacturing cost, so it currently occupies a dominant position in the display field. [0003] With the continuous development of display technology, anti-peep liquid crystal displays with wide viewing angle (sharing mode) and narrow viewing angle (anti-peeping mode) switching between each other have been applied. When the anti-spy LCD display is switched to a narrow viewing angle mode, a narrower viewing angle can be obtained to prevent peeping; when the anti-peeping LCD display is switched to a wide viewing angle mode, a wider viewing angle can be obtained to share information Purpose. When measuring the brightness of the anti-peeping liqui...
