Problems solved by technology

[0004] However, the LED surface light source backlight display in the prior art includes an LED surface light source and a display panel, and the LED surface light source and the LED of the display panel are electrically connected through a flexible printed circuit assembly (FPCA). The LED driver IC is usually arranged on the flexible circuit board assembly, and the flexible circuit board assembly needs an additional connector to electrically connect the LED driver IC to the LED chip on the LED surface light source, which undoubtedly compresses the space of the flexible circuit board assembly. In addition, it is difficult to wire the LED driver IC to electrically connect the LED chip on the LED surface light source, and the above problems greatly increase the production cost.

Abstract

The invention provides a liquid crystal display, which comprises a MINI LED substrate, a plurality of MINI LED chips arranged on one side surface of the MINI LED substrate, a MINI LED driving IC arranged on the other side surface of the MINI LED substrate and a fluorescent film covering the plurality of MINI LED chips, wherein the MINI LED driving IC drives the plurality of MINI LED chips to emitlight, compared with the prior art, the MINI LED driving IC is not required to be arranged on a flexible circuit board assembly, a connector is saved, the design space for compressing the flexible circuit board assembly is avoided, the difficulty of electrically wiring the MINI LED driving IC and the plurality of MINI LED chips is reduced, so that the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display. Background technique [0002] With the development of display technology, liquid crystal display (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, TVs, Various consumer electronic products such as personal digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module (Backlight Module). The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by elec...
