A liquid crystal display module and its preparation method

Abstract

The invention discloses a liquid crystal display module. The liquid crystal display module comprises an array substrate, a flexible printed circuit board and a driving circuit. The flexible printed circuit board is electrically connected with the driving circuit and used for transmitting data and signals to the driving circuit. The array substrate comprises a glass substrate and an anti-jamming circuit. The driving circuit is located on the glass substrate. The anti-jamming circuit is directly formed on the glass substrate, electrically connected between the flexible printed circuit board and the driving circuit and used for performing decoupling and filtering processing on the data and the signals. According to the liquid crystal display module, the area and thickness of the flexible printed circuit board can be reduced, and the requirement for lightening and thinning design of the liquid crystal display module are easily met. The invention further provides a manufacturing method of the liquid crystal display module.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display module and a preparation method of the liquid crystal display module. Background technique [0002] LCD module is an important part of LCD electronic products, please refer to figure 1 , figure 1 It is a structural schematic diagram of a liquid crystal display module in the prior art. Such as figure 1 As shown, the liquid crystal display module usually includes a liquid crystal panel 10', a driving circuit 20' and a flexible circuit board 30', and the flexible circuit board 30' is the data link between the main board (not shown) and the liquid crystal panel 10'. And a signal transmission bridge, which transmits the data and signals from the motherboard to the driving circuit 20', and then to the liquid crystal panel 10'. In order to prevent the transmitted data and signals from being disturbed, the flexible circuit board 30' is often provided wit...

AI Technical Summary

Problems solved by technology

[0003] However, as people's requirements for product performance become higher and higher, the difficulty of arranging anti-interference circuits such as voltage stabilization, decoupling and filtering, especially the capacitors in them, on the flexible circuit board also increases.

In addition, the arrangement of multiple capacitors on the flexible circuit board will occupy a large amount of area, making the flexible circuit board larger, especially the height and thickness of the capacitor itself, which will not only increase the thickness of the liquid crystal display, but also make it difficult for the liquid crystal display module to It meets the requirements of thinner and thinner, and when the LCD module is assembled into mobile phones or other electronic products using LCD modules, it also requires more space, which makes it difficult for mobile phones or other electronic products using LCD modules to achieve thinner and lighter customized design requirements
