N-in-one full-color display device with mask

Abstract

The invention discloses an N-in-one full-color display device with a mask, and aims to solve the problems of non-condensation, non-collision resistance and light channeling among pixel points of a product and the problems that a bracket of a structural product is high in processing difficulty and low in efficiency, pins have high and low pins, the pins are exposed at two sides and the wiring difficulty of a PCB is high. The device comprises: a substrate; a plurality of chip mounting areas arranged on the upper surface of the substrate; a plurality of bowls and cups are arranged on the mask; and a plurality of pins arranged on the lower surface of the substrate. Each chip mounting area is used for fixing a plurality of single-color or multi-color light-emitting chips; and the number of the bowls is matched with that of the chip mounting areas. The beneficial effects of the device are that the mask is pasted on the substrate, and the substrate is provided with the bowl cups, thereby achieving the effects of preventing light channeling between pixel points, condensing light, improving brightness and preventing collision; and by arranging the pins at the bottom of the substrate, the problems that the pins are exposed due to the arrangement mode of the pins on the two sides, and wiring of a PCB drawing board of the display screen module is complex can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to an N-in-1 full-color display device with a mask. Background technique [0002] The TOP bracket of traditional full-color display LED is a bottom metal structure plus a single plastic bowl. When a single bowl bracket is made into a small-sized bracket, due to size restrictions, it cannot be made smaller; in addition, the cost of a single bowl bracket has room for reduction Limited; at the same time, due to the many lead-out pins of a single cup bracket, the airtightness of the bracket cup is poor. After the finished product is packaged, external moisture can easily enter the inside of the cup from the bracket pins, resulting in poor airtightness of the finished LED package and easy failure. Therefore, there are still defects in current products and technologies that need to be resolved. At present, LED full-color N-in-1 display devices, taking 4-in-1 products as an exampl...

Problems solved by technology

[0004] The present invention is mainly to solve the problems of non-condensing, intolerant of collision, and light channeling between pixels, as well as the difficulty and low efficiency of the bracket processing of structural products, the pins have high and low pins, and the pins are exposed on both sides and the PCB. For the problem of difficult wiring, we provide an N-in-1 full-color display device with a mask, which can prevent light crossing between pixels, focus light to improve brightness, and prevent collisions. It can effectively solve the problem of pin arrangement on both sides The problem of exposed pins and complicated wiring on the PCB drawing board of the display module caused by the method; and effectively solve the problem of high and low feet caused by bending
