Problems solved by technology

[0003] Due to its structural characteristics, LCD panel TVs have the following deficiencies: 1. Insufficient brightness; 2. Long LCD response time; 3. Insufficient LCD color reproduction; , Light-emitting diode, referred to as LED, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light
Although this process has the advantages of small size, large emission angle, good luminous uniformity, and high reliability, it still cannot meet the requirements of LED panels as TV screens.

Abstract

The invention relates to an LED flat panel display unit with a drive control device, which has the advantages of extremely small LED pixel spacing, low cost and good control performance. In the technical scheme, the LED flat panel display unit is characterized by consisting of an upper insulating circuit substrate, a middle multi-level insulating circuit substrate and a lower insulating circuit substrate, wherein the upper insulating circuit substrate, the middle multi-level insulating circuit substrate and the lower insulating circuit substrate are compressed as a whole at a high temperature, and the outer surfaces of the upper insulating circuit substrate, the middle multi-level insulating circuit substrate and the lower insulating circuit substrate are respectively provided with epoxy resin or silicone resin filling cover. The invention also discloses a production method of the LED flat panel display unit with the drive control device.

Description

technical field [0001] The invention belongs to the field of LED flat-panel display units, in particular to an LED flat-panel display unit with a self-contained drive control device with extremely small LED pixel spacing, low cost, good control performance, and easy installation and disassembly, and a production method. The LED flat-panel display unit with its own drive control is mainly used in LED panel TVs, and can also be used in LED full-color displays. Background technique [0002] Since the television was invented, the upgrading of television products has never stopped, and new products emerge in an endless stream. At present, the most advanced TV products are LCD TVs. The best-selling LED backlight TVs in the domestic and foreign markets all belong to the category of LCD LCD TVs. LED backlight TVs are not "LED TVs" in the true sense. The best LED TVs should be LED direct imaging TVs. LED backlight TVs are often called LED TVs. They are actually LCD TVs that use LED...
