Problems solved by technology

In this liquid crystal display device, the first flexible circuit board 20' is folded from the top surface of the backlight module 1' along one side of the backlight module 1' to the bottom surface of the backlight module 1', and partly has height-limiting components. The driving circuit 30' of 31' is folded back to the bottom surface of the backlight module 1', so that the position of the height-limiting component 31' becomes the highest point of the bottom surface of the backlight module 1', which affects the thickness of the liquid crystal display device and makes it easy for the liquid crystal display interference within the device
There are mainly two solutions to this problem in the prior art: one is to adjust the height of the drive components 31' on the drive circuit 30', which will increase the product cost and affect the reliability of the drive; the other is to optimize the liquid crystal display The stacking structure of the device requires perforation or thinning of the mechanical components (such as the front frame and the middle frame). This method will affect the thickness specification of the whole machine and increase the product cost

Abstract

The invention provides a liquid crystal display device which comprises a liquid crystal display panel (2) and a backlight module (1) arranged at the bottom of the liquid crystal display panel (2), wherein a first flexible circuit board (20) is electrically connected with a second flexible circuit board (15), a height limiting element (22) in a driving circuit of the liquid crystal display panel and a backlight source driving circuit are arranged on the second flexible circuit board (15) together, and meanwhile, an avoiding hole (111) is formed in a glue frame (11) of the backlight module (2) and is used for accommodating the height limiting element (22), so that the thickness of the liquid crystal display device is effectively reduced and the competitiveness of the products is promoted.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device. Background technique [0002] A liquid crystal display device (Liquid Crystal Display, LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc., occupy a dominant position in the field of flat panel display. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module (Backlight Module). The working principle of the liquid crystal panel is to apply a driving voltage on the thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate) and the color filter substrate (ColorFilter, CF) to control the rotation direction of the l...
