Embodiment Construction

[0025] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0026] The present invention provides a backlight module for wide color gamut curved display, please refer to Figure 1-3 , is the first embodiment of the backlight module of the present invention. In this embodiment, the backlight module includes a heat dissipation bracket 1, a main light source 21, a compensation light source 22, a light guide plate 3, and a mounting seat 7. The heat dissipation bracket 1 includes a first bottom plate 11 and several first side plates 12 connected to the first bottom plate 11, the light guide plate 3 has two opposite short sides 31 and an opposite side between the two short sides 31 and connected to the two short sides 31 The two long sides 32 of the first side plate 12 are set corresponding to the short side...

Abstract

A backlight module, applied to a wide-gamut curved display. Aiming at the problem of insufficient backlight brightness of quantum dot technology, compensation light sources (22) are additionally arranged in a backlight module, the compensation light sources (22) are arranged on at least one side of two sides of two corresponding long edges (32) of a light guide plate (3), at least one compensation light source (22) is located on one side of each long edge (32), and the compensation light sources (22) are white light LED lamp bars or other monochromatic LED light bars compensated according to a gamut demand. By arranging the compensation light sources (22), the backlight module compensates a certain luminous flux, so as to improve the brightness or gamut performance of a display, thereby being beneficial to the large size design of a wide gamut curved display, and also being beneficial to the reduction of the costs of an optical film set.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module for wide color gamut curved displays. Background technique [0002] Currently, display devices are mainly flat panel displays. Most liquid crystal modules used in flat panel displays use TFT-LCD (Thin Film Field Effect Transistor LCD) technology. TFT-LCD is a non-active light-emitting display. Usually, a white backlight module (Backlight Module) provides uniform system brightness, and then obtains rich color display through a color filter (Color Filter). [0003] Because the retina of the human eye is curved, viewing a purely flat screen is actually "distorted", while a curved screen can intuitively map the screen to the brain at the same angle, so that the "flat screen" brought to the audience by the flat screen can be skipped. —Curved surface-flat” conversion link, users can truly feel the theater-level audio-visual experience brought by the curved screen ...
