Problems solved by technology

Furthermore, the heat dissipation of the direct-type design is high, and the heat dissipation problem needs to be solved by using a metal core printed circuit board (MCPCB), which leads to an increase in cost
In addition, the LED light bar is assembled by screw lock, the assembly process is time-consuming, resulting in prolonged process time
[0004] In order to meet the uniformity of light mixing, the light mixing distance of general displays is long, and it is impossible to realize a display with narrow borders
If it is made into a display with a narrow frame, in order to improve the brightness and darkness of the incident light, it is necessary to increase the number of LEDs, or to design the microstructure at the light entrance of the light guide plate; however, these two methods will increase the manufacturing cost

Abstract

The invention relates to a displayer. The displayer comprises a display panel, a light guide plate and a first light-emitting unit. The light guide plate is arranged on one face of the display panel and is provided with a first light inlet face, and the first light-emitting unit is arranged on the first light inlet face of the light guide plate and comprises a plurality of first light-emitting diodes. An angle is formed between the light outlet face of each first light-emitting diode and the first light inlet face of the light guide plate, and the angle ranges from 2 degrees to 60 degrees.

Description

technical field [0001] The invention relates to a display, in particular to a display that adjusts the angle between the light-emitting surface of a light-emitting diode and the light-incoming surface of a light guide plate to improve the effective light-emitting area and realize narrow frame. Background technique [0002] At present, the design of LED backlight modules can be divided into side-view design (side-view), which is suitable for notebook computers, or top-view design (top-view), which requires a large space for light mixing. The latter is mostly used in large-size panels. on the design. The design of LED backlight modules can be divided into: a side-view design (side-view), which is suitable for small-sized displays such as notebook computers, or a direct-view design (top-view), which requires a large space for light mixing. The latter is mostly used on large displays. [0003] The edge-lit LED backlight unit (BLU) of a large-size display uses a long LED light ...
