Driving printed circuit board and liquid crystal display

Abstract

The invention relates to a driving printed circuit board and a liquid crystal display. The driving printed circuit board is a flexible printed circuit board on which a liquid crystal display panel driving circuit and a backlight module driving circuit are arranged; the backlight module driving circuit is used for attaching a light source; and when the driving printed circuit board is assembled, the part provided with the backlight module driving circuit is bent into a backlight module. The liquid crystal display comprises a main frame, and a liquid crystal display panel, the driving printed circuit board and the backlight module which are embedded into the main frame, wherein the driving printed circuit board is the flexible printed circuit board on which the liquid crystal display panel driving circuit and the backlight module driving circuit are arranged; the light source is attached to the backlight module driving circuit; and the part provided with the backlight module driving circuit is bent into the backlight module. The technical scheme of the invention integrates the backlight module driving circuit and the liquid crystal panel driving circuit on a printed circuit board so as to simplify the process and improve assembling efficiency.

Description

Technical field [0001] The invention relates to a backlight module structure in a liquid crystal display, in particular to a driving printed circuit board and a liquid crystal display. Background technique [0002] At present, in the flat panel display (Flat Panel Display; hereinafter referred to as: FPD) technology, the liquid crystal display (Liquid Crystal Display; hereinafter referred to as: LCD) is dominant, and the transmissive LCD is the mainstream of the current LCD technology. Since the liquid crystal itself does not emit light, the backlight module is an essential part of the transmissive LCD. [0003] Transmissive LCDs can generally be divided into side-light type and direct-light type according to the different installation positions of the backlight source. The use of side-light type backlight modules is an important means to realize LCD thinning. [0004] figure 1 Is a schematic structural diagram of an edge-lit liquid crystal display in the prior art, figure 2 It is ...

Problems solved by technology

In the above process, an independent step of attaching the lamp group is required. Generally, the double-sided adhesive is applied on the printed circuit board and then pasted on the backlight frame, which makes the assembly process of the backlight module complicated, and the complex process leads to High bit accuracy requirements, low assembly efficiency, and easy to produce defective products
