Abstract
Description
Technical Field
[0001] The utility model relates to a mobile phone display module, more specifically, to a mobile phone display module which is convenient for viewing the identification of electronic devices. Background Art
[0002] The mobile phone display module is mainly composed of a display screen, a backlight, an FPC, an IC, etc. The display screen 1000 is a carrier for displaying images; the FPC2000 connects the display screen 1000 and the mobile phone motherboard together. The mobile phone motherboard provides the IC with corresponding drive and control signals through the FPC2000. The IC outputs corresponding control signals to make each pixel of the display screen display the required image, and the backlight is used to provide light source.
[0003] like Figure 7 As shown, a certain number of electronic components 2300 (capacitor C, resistor R, anti-static TVS tube) are usually attached to FPC2000 to boost, filter, and protect IC power signals from electrostatic discharge. When product samples are made for optimization and debugging or after-sales analysis of defective products, it is necessary to measure the voltage pairs of these components to confirm whether the relevant circuits are normal.
[0004] Since there are usually many electronic components 2300, as many as more than 40, in order to quickly find the corresponding device that needs to be tested for measurement, the device identification S00 of the corresponding row and column is usually silk-screened on the attachment of the FPC electronic component area to assist in the search without opening the original circuit design drawing.
[0005] However, this device identification S00 requires additional white oil material, which is costly. Moreover, since the visible area of the device identification S00 is limited, it is sometimes difficult for workers to see it clearly.
[0006] Chinese utility model patent document CN209376011U discloses a flexible circuit board for a mobile phone backlight assembly with an optimized white oil layer, which includes a strip FPC body, and the lower edge of the strip FPC body has a vertical downward extension surface near one end, characterized in that: a layer of white oil layer is attached to the upper surface of the strip FPC body, and the upper edge and the two end edges of the white oil layer are respectively spaced 0.2 mm from the corresponding edges of the strip FPC body, that is, the upper edge and the two side edges of the strip FPC body form a white oil-free spacing zone with a width of 0.2 mm inwardly.
[0007] Obviously, when punching the entire page, the patent will not punch the white oil layer, and the white oil layer is separated from the edge of the FPC. In this way, when a single FPC is torn off, there is no white oil at the connection point at the edge of the FPC, which is easy to tear off and prevents the white oil from falling off. This structure cannot solve the existing device identification problem. Utility Model Content
[0008] Based on this, it is necessary to provide a mobile phone display module for conveniently viewing the identification of electronic devices in view of the above technical problems. The mobile phone display module for conveniently viewing the identification of electronic devices includes a display screen, an FPC board and a mobile phone motherboard. An upper connector is provided at one end of the FPC board, and a lower connector is provided at the other end of the FPC board. The upper connector is connected to the display screen, and the lower connector is connected to the mobile phone motherboard. An IC module is provided on the display screen, and the IC module drives the display screen to display the required picture. Several electronic devices are distributed on the FPC board, and the relative distribution positions of the electronic devices constitute an electronic device distribution data module, which is stored in the IC module. When it is necessary to test the corresponding device of the product, the display screen 1 is lit, and the identification silk screen picture is directly called and displayed on the display screen 1, and the measurement can be compared. Since it is no longer necessary to silk screen the component identification on the FPC board 2, the production process of the FPC board 2 is greatly simplified, white oil materials are saved, and material costs are reduced. Moreover, the silk screen picture displayed on the display screen 1 will be magnified many times more than the FPC physical silk screen, which is clearer and convenient for workers to quickly view.

[0036] As described in the background technology, the prior art for mobile phone display modules is mainly composed of a display screen, a backlight, an FPC, an IC, etc. The display screen 1000 is a carrier for displaying images; the FPC 2000 connects the display screen 1000 and the mobile phone motherboard together, and the mobile phone motherboard provides the corresponding drive and control signals to the IC through the FPC 2000. The IC outputs the corresponding control signal so that each pixel of the display screen displays the required image, and the backlight is used to provide a light source. A certain number of electronic components 2300 (capacitor C, resistor R, anti-static TVS tube) are usually attached to the FPC 2000 to boost, filter, and protect the IC power supply signal from electrostatics. When the product samples are made for optimization and debugging or after-sales analysis of defective products, it is necessary to measure the voltage pairs of these components to confirm whether the relevant circuits are normal. Since there are usually many electronic components 2300, with as many as more than 40, in order to quickly find the corresponding device to be tested for measurement, the device identification S00 of the corresponding row and column is usually printed on the FPC electronic component area to assist in the search, without opening the original circuit design drawing. However, this device identification S00 requires additional white oil material, which is costly. Moreover, due to the limited visible area of the device identification S00, it is sometimes difficult for workers to see clearly.

A plurality of electronic devices 23 are distributed on the FPC board 2, and the relative distribution positions of the electronic devices 23 constitute an electronic device distribution data module S, and the electronic device distribution data module S is stored in the IC module 11.
[0038] Through the above structural design, the relative distribution position of the electronic device 23 constitutes the electronic device distribution data module S. The main method is to make a picture by silk-screening the identification of the electronic device 23, and then convert the picture into corresponding binary data to obtain the electronic device distribution data module S, and finally store it in the storage unit 111 of the IC module 11 by burning. When it is necessary to test the corresponding device of the product, light up the display screen 1, directly call and display the identification silk-screen picture on the display screen 1, and then measure it by comparison.
