Problems solved by technology

[0003] With the development of technology, curved liquid crystal display screens emerged as the times require. However, the LED chips in the curved surface backlight module in the curved surface liquid crystal display have the same light emitting angle, which makes the light emission of the curved surface backlight module uneven, resulting in curved liquid crystal display. The display effect of the screen is reduced

Embodiment Construction

[0021] A specific implementation manner of a curved display device provided by an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] The inventor found in the research that, for the LED substrate in the backlight module, if the curvature of any position in the LED substrate 11 is substantially the same, the light-emitting angle of each LED chip v can be set to θ1. At this time, the LED The luminance of the substrate 11 can be considered uniform, such as figure 1 shown in the left figure.

[0023] If the LED substrate 11 is set to a curved surface, such as f...

Abstract

The invention discloses a curved display device and relates to the technical field of display. In an embodiment of the present invention, the curved surface display device includes a curved surface backlight module, the curved surface backlight module includes a curved surface LED substrate, and the curved surface LED substrate includes a plurality of LED chips arranged in an array; by setting the light emitting angle of each LED chip, That is, setting the light-emitting angles of at least some of the LED chips to be different can improve the uniformity of light-emitting brightness of the curved surface backlight module, thereby helping to improve the display effect of the curved surface display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved display device. Background technique [0002] A liquid crystal display is a non-self-illuminating device, which requires a backlight module to provide a backlight to realize the display function. At present, LED substrates with a plurality of mini LED chips arranged in an array are mostly used to form a backlight module. This kind of backlight module can make the liquid crystal display screen have a high dynamic range screen effect, and the display screen is more delicate, etc. features. [0003] With the development of technology, curved liquid crystal display screens emerged as the times require. However, the LED chips in the curved surface backlight module in the curved surface liquid crystal display have the same light emitting angle, which makes the light emission of the curved surface backlight module uneven, resulting in curved liquid crystal display. The displ...
