AI Technical Summary
When displaying a partial image, the backlight of the existing VA negative display screen allows light to pass through to other viewing angles, affecting the contrast and making it impossible to achieve a seamless black effect from all viewing angles. Furthermore, existing improvement methods result in uneven background color or reduced brightness.
It adopts a combination structure of upper polarizer, lower polarizer, orange color film, upper brightness enhancement film and lower brightness enhancement film, combined with specific angle adjustment, and the background color of LCD screen is bluish. It reduces the brightness of the side viewing angle through optical convergence, and improves the blackness of the background color and the display brightness.
It achieves a seamless black display effect from all viewing angles, while ensuring high brightness and high contrast, thus enhancing the user experience.

Description
TECHNICAL FIELD
[0001] The utility model relates to display screen technical field, concretely is a full viewing angle integral black's display screen. BACKGROUND
[0002] At present, the VA negative screen on the market needs to be lightened when displaying a local picture, and the backlight is matched with the picture display, but the other non-displaying areas of the liquid crystal screen will cause the light source of the backlight to be transparent due to the large viewing angle light transmission characteristics of the liquid crystal display screen, resulting in bottom color light transmission. The upper and lower polarizing sheets cannot achieve the light transmission rate of the viewing angle direction. Therefore, when the backlight is working, other viewing angles will transmit light, affecting the contrast ratio, and the full viewing angle integral black effect cannot be achieved. The prior art generally increases black silk printing in the non-pattern area to improve this problem, but it will form a significant bottom color difference with the pattern area, resulting in uneven bottom color. There is also a method of reducing the backlight brightness, but the backlight brightness is low, the display picture brightness is also low, and the contrast ratio is poor.
[0003] Therefore, in order to correct the above-mentioned defects, a full viewing angle integral black display screen is proposed. CONTENT OF THE UTILITY MODEL
[0004] The utility model solves the technical problem of providing a full viewing angle integral black display screen.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a full viewing angle integral black display screen, which comprises an upper polarizing sheet, an LCD liquid crystal display screen, a lower polarizing sheet, an orange color film, a light enhancement film and a backlight from top to bottom.
[0006] Further, the light enhancement film comprises an upper light enhancement film and a lower light enhancement film interconnected.
[0007] Further, the upper polarizing sheet further has a tempered glass cover plate on the upper part.
[0008] Compared with the prior art, the utility model has the beneficial effects that: the device realizes high contrast display effect of ensuring black bottom color and high display picture brightness by adjusting the glass bottom color, orange color film, upper and lower polarizing sheets and upper and lower light enhancement to a specific angle.

[0012] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0013] The utility model provides a technical scheme:
[0014] Please refer to Figure 1 A display screen with full viewing angle and integral black, the display screen comprises, from top to bottom, a tempered glass cover plate 1, an upper polarizing sheet 2, an LCD liquid crystal display screen 3, a lower polarizing sheet 4, an orange color film 5, an upper light enhancement film 6, a lower light enhancement film 7 and a backlight 8.
[0015] The LCD liquid crystal display screen 3 is controlled to adjust the liquid crystal delay amount, the bottom color of the LCD liquid crystal display screen 3 is blue, the orange color film 5 is used to improve the display screen bottom color blackness, the upper polarizing sheet 2 and the lower polarizing sheet 4 are used to improve the display screen bottom color blackness by adjusting the deflection angle. The upper light enhancement film 6 is placed at 45 degrees and the lower light enhancement film 7 is placed at 135 degrees, so that the left and right large-angle light is gathered into the light perpendicular to the screen. The brightness of the side viewing angle is reduced, and the side viewing angle blackness is improved.
[0016] Embodiment one
[0017] Only the on-off switch indication icon is lighted, the panel is directly operated without turning on the light at night, the non-lighted area of the panel is not light-transmitting, the personnel rest is not affected by the light transmission of the panel, and the user experience is improved.
[0018] Embodiment two
[0019] The bottom color blackness is improved by overlapping the orange light of the backlight with the blue bottom color of the single LCD, the backlight is placed by crossing two layers of light enhancement films to reduce the left and right light sources, and the backlight surface is provided with an orange color film.
[0020] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
