Problems solved by technology

[0005] Neither the control of the LED lighting angle nor the design of the three-dimensional reflector can control the light within a relatively small range, so it will cause light at a large angle to enter the surrounding light emitting area
like figure 2 , the light 50 of the LED will diverge to the surrounding LED light source area, affecting the luminous brightness of the surrounding area

Abstract

The embodiment of the present invention discloses an optical module and a display device, comprising: a base substrate, a plurality of light sources, the light sources are arranged on the base substrate and are electrically connected to the base substrate; a plurality of three-dimensional reflections The three-dimensional reflectors are arranged on the base substrate, and in the direction perpendicular to the base substrate, each of the three-dimensional reflectors surrounds at least one of the light sources; grating film, the grating film The sheet includes at least two axially intersecting opaque gratings, and the grating diaphragm is located on a side of the three-dimensional reflector away from the base substrate. The invention controls the angle of light divergence by arranging gratings in the optical module, thereby eliminating the large halo phenomenon of the backlight light source, realizing the effect of regional dimming, and controlling the light within the corresponding range of the three-dimensional reflector, and not in the Adjacent areas produce mixed light; greatly improve the contrast of optical modules and display devices.

Description

technical field [0001] The invention belongs to the technical field of display device control, and in particular relates to an optical module and a display device. Background technique [0002] The liquid crystal display panel displays images by driving electrodes of thin film transistors, and does not emit light by itself, so the backlight that provides all the light sources for the liquid crystal display panel plays a very important role. Depending on the location of the backlight source, the backlight module can be divided into two types: direct-type backlight and edge-type backlight. When a large-sized LCD uses an edge-type backlight, the cost of the light guide plate is proportional to its size and weight. , and indicators such as the uniformity of the surface light source and the brightness reaching the LCD screen will decrease, while the direct-type backlight module has little light loss due to the direct vertical upward light source, which saves power and increases b...
