Backlight plate, LED module and electronic equipment

Abstract

The invention provides a backlight plate, an LED module and electronic equipment, the backlight plate comprises a PCB and an LED array, the PCB comprises a first plate body and a second plate body, the first plate body and the second plate body are arranged in a harpoon structure, one side of the first plate body extends towards the second plate body to form a first harpoon tooth part, and the other side of the first plate body extends towards the second plate body to form a second harpoon tooth part; one side of the second plate body extends towards the first plate body to form a second harpoon tooth part, and the LED arrays are evenly distributed on the first harpoon tooth part and the second harpoon tooth part. The PCB is arranged to be the first board body and the second board body which are of the harpoon structure, the use area of the board is reduced, the effective utilization rate of the board is increased, and the cost of the PCB is reduced when the LED heat dissipation requirement is met; meanwhile, the harpoon tooth parts are uniformly arranged at intervals, so that the internal stress of the backlight plate is reduced, the warping of the backlight plate is improved, and the shipment yield of a backlight plate factory and the process yield of SMT (Surface Mount Technology) are improved; makeup production is achieved through the first plate body and the second plate body, the distribution number of LEDs is increased, and the production efficiency of a backlight plate factory and the surface mounting efficiency of SMT are improved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a backlight panel, an LED module and electronic equipment. Background technique [0002] With the rapid development of the semiconductor industry and the improvement of people's living standards, the LED display industry has experienced long-term development, and the technical route is constantly changing, from traditional LCD+LED backlight to LCD+Mini LED backlight. [0003] 2021 is known as the first year of Mini LED mass production. Many TV terminal brand manufacturers at home and abroad have launched a variety of new products, and the attention of Mini LED backlight products has greatly increased. The main competitor of Mini LED backlight is OLED, which has already entered the high-end TV market first. Facing the price-sensitive consumer market, cost may become the key to the success of Mini LED backlight. However, PCB occupies a large proportion in the cost of Mini L...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 As shown, the current Mini LED backlight usually uses a square sheet-shaped backplane structure design, while the LED array occupies a large area, and there are problems such as large waste of PCB boards, low effective utilization, high cost, and low SMT mounting efficiency.
