Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0021] figure 2 It is a schematic diagram of the structure of the brightness enhancement film of the present invention. The brightness enhancement film includes a substrate 100, a plurality of first microstructures 101 located in the middle region of the substrate 100, and a plurality of second microstructures 102 located at both ends of the substrate. When the brightness enhancement film is used in a curved display, the first microstructure 101 of the brightness enhanc...

Abstract

The invention discloses a brightness enhancement film and a curved surface displayer. The curved surface displayer comprises a liquid crystal panel and the brightness enhancement film. The brightnessenhancement film comprises base material and multiple first microstructures which are arranged in the middle area of the base material and multiple second microstructures which are arranged on the twoends of the base material. The first microstructures of the brightness enhancement film are corresponding to the normal display area of the liquid crystal panel. The second microstructures of the brightness enhancement film are corresponding to the bending area of the liquid crystal panel. Different angles of microstructures are designed in different areas of the brightness enhancement film to bematched with the bent liquid crystal panel so that the light is enabled to be vertically incident to the bent liquid crystal panel as much as possible, curved surface displayed can be realized without bending the backlight module group and the problem of non-uniform light emission of curved surface display can be improved.

Description

technical field [0001] The invention belongs to the technical field of curved displays, in particular to a brightness enhancement film and a curved display. Background technique [0002] Since the curved display can display a surround stereo picture effect, which is better than the traditional flat display, the application of the curved display is also becoming wider and wider. At present, when using a thin film transistor liquid crystal display panel as a curved screen, the backlight module 20 and the liquid crystal display panel 10 are generally bent at the same time, such as figure 1 As shown, and then achieve the effect of curved surface display. The existing design has the following disadvantages: After the backlight module is bent, each optical film is affected, resulting in uneven light emission; the liquid crystal display panel and the backlight module are bent at the same time, the precision is not easy to control, and the process difficulty is increased.
