Problems solved by technology

[0003] The backlight module FPC of the existing mobile phone is designed with the A and K solder feet of the backlight source. During the assembly process of the display screen, the A and K solder feet on the backlight module FPC need to be welded to the LCD FPC first, and then the LCD The display FPC is welded to the main board of the mobile phone. In order to ensure the welding quality, the LCD FPC needs to be fixed to the main board before the welding of the LCD FPC and the mobile phone main board. After the FPC is bent, fix it with the main board with double-sided adhesive tape. Due to the small curvature and large elastic force of the FPC of the LCD display, the FPC of the LCD display and the main board of the mobile phone are not fixed firmly, which directly affects the welding quality of the FPC of the LCD display and the main board of the mobile phone. Thus affecting the display performance of the mobile phone display

Abstract

The invention provides a simple display which includes a liquid crystal display, a backlight module, and a FPC. The backlight module is disposed below the liquid crystal display. The FPC is integrated with lines of the backlight module and the liquid crystal display. The FPC is disposed at one ends of the backlight module and the liquid crystal display. The FPC is provided with a U-shaped ring-shaped notch thereon. The internal side of the bottom part of the U-shaped ring-shaped notch is provided with a pin which is connected to a display glass of the liquid crystal display. According to the invention, the simple display obviates the need for welding steps required in assembly the liquid crystal display and the FPC and the backlight module and the FPC, saves welding cost, reduces elastic force of the FPC in the bending process, such that the FPC is firmly fixed in the welding process and the disqualification rate of welding is reduced.

Description

technical field [0001] The invention relates to the field of mobile phone manufacturing, and more specifically, the invention relates to a simple display screen. Background technique [0002] The display screen of an existing mobile phone generally includes a liquid crystal display 1', a backlight module 2', a liquid crystal display flexible circuit board 3', a backlight module flexible circuit board 4', figure 1 It is a structural schematic diagram of an existing conventional mobile phone display screen, please refer to figure 1 shown. Flexible Printed Circuit (FPC) is a highly reliable and excellent flexible printed circuit board, which has the characteristics of high wiring density, light weight, thin thickness and good bendability. [0003] The backlight module FPC of the existing mobile phone is designed with the A and K solder feet of the backlight source. During the assembly process of the display screen, the A and K solder feet on the backlight module FPC need to b...
