Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a metal PIN connection display screen with a protection function pin. Background Art

[0002] Metal PIN connection is a common connection method and is also the connection method of most LCD screens. In fact, the metal PIN is installed on the outer lead of the bottom glass of the LCD screen.

[0003] As attached Figure 5 The LCD screen shown in the figure is connected by metal PIN connection. Since the driver IC requires only a few functional pins, including RESET, SDA, SCL, VDD and VSS, the connection of five pins alone is often not reliable enough when connected to the motherboard. In addition, when the LCD screen is stored or installed, the pins on the side are always outside, which are also the pins most susceptible to external collision and extrusion. Once the functional pins are damaged, the connection between the display screen and the motherboard may be unstable or even fail. Therefore, in order to improve the reliability of the connection between the functional pins and the motherboard, and to protect the reset signal pins and ground wires on the side, we have specifically designed a metal PIN connection display screen that protects the functional pins. Utility Model Content

[0006] As a further solution of the utility model: the functional PIN pin includes a reset signal pin, a serial data signal pin, a serial clock signal pin, a power line and a ground line, and the reset signal pin, the serial data signal pin, the serial clock signal pin, the power line and the ground line are all clamped in the connecting part.

[0007] As a further solution of the utility model: the reset signal pin, serial data signal pin, serial clock signal pin, power line and ground line are arranged between two DUMMY PIN pins, and the two DUMMY PIN pins are respectively located outside the reset signal pin and outside the ground line.

[0008] As a further solution of the utility model: gaps are arranged among the reset signal pin, the serial data signal pin, the serial clock signal pin, the power line, the ground line and the DUMMY PIN pin.

[0009] As a further solution of the utility model: the length and size of the DUMMY PIN pin are the same as those of the functional PIN pin.

[0010] As a further solution of the utility model: the two clips are designed to be S-shaped structures, and the sides of the two clips close to each other are both arc protrusions.

[0011] As a further solution of the utility model: the upper glass is installed on the top of the lower glass, the upper polarizer is installed on the top of the upper glass, and the lower polarizer is installed on the bottom of the lower glass.

[0012] As a further solution of the utility model: the connecting portion is arranged on one side of the lower glass, and the functional PIN pin and the DUMMY PIN pin are both encapsulated by UV glue at the connecting portion.

[0013] As a further solution of the utility model: black silica gel is glued and fixed to the top of the lower glass and at a position on one side of the upper glass, and a driver IC installed on the lower glass is arranged in the black silica gel.

[0014] As a further solution of the utility model: the functional PIN pin is connected to the driver IC through an ITO lead on the glass.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] In the present application, the functional PIN pin is set in the middle of the connecting part through the setting of the connecting part, and a non-functional DUMMY PIN pin is added on both sides of the functional PIN pin. These two DUMMY PIN pins only need to be clamped and connected with the lower glass. Unlike the functional PIN pin, it is not necessary to connect and conduct with the driver IC through the ITO lead on the glass. Adding two DUMMY PIN pins can effectively improve the connection reliability between the display screen and the motherboard. At the same time, placing the functional PIN pin in the middle can effectively avoid external collision and extrusion directly acting on the functional PIN pin, and finally play a role in protecting the functional PIN pin.
