Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal display screens, and in particular to a TFT liquid crystal display screen. Background Art

[0002] TFT (Thin Film Transistor) LCD is a thin film transistor LCD, which is a type of active matrix liquid crystal display (AM-LCD). It is mainly used in industries such as computers, video terminals, communications and instrumentation. The main application areas are notebook computers, desktop computer monitors, workstations, industrial monitors, global satellite positioning systems (GPS), personal data processing, game consoles, video phones, portable VCDs, DVDs and other portable devices.

[0003] In the TFT LCD cutting process, in order to prevent glass fragments or static electricity from affecting the TFT LCD wiring, a whole layer of ITO is generally covered on all wiring as protection. However, in the substrate process, a whole layer of ITO is prone to short-circuiting with the wiring underneath when static electricity is present, thereby causing the TFT LCD chip medium to be broken down or burned. Utility Model Content

[0004] In order to solve the deficiencies in the prior art, the purpose of the present application is to provide a TFT liquid crystal display screen to reduce the impact of static electricity on the TFT liquid crystal display screen.

[0005] To achieve the above-mentioned purpose, the present application provides a TFT liquid crystal display screen, including a display screen body, on which a driver IC for driving the display screen body is disposed, the driver IC is electrically connected to the display screen body via a connecting line, and an ITO strip covering the connecting line is disposed on one end of the connecting line close to the driver IC.

[0006] Furthermore, each connecting line corresponds to an ITO strip.

[0007] Furthermore, gaps are left between the ITO strips on adjacent connection lines.

[0008] Furthermore, the extending direction of the ITO strip is consistent with the extending direction of the corresponding connecting line.

[0009] Furthermore, the length of the ITO strip is at least 1 / 10 of the corresponding connecting line.

[0010] Furthermore, the display screen body includes a display area and a non-display area, the display area is electrically connected to the driver IC via a signal connection line, and the non-display area is electrically connected to the driver IC via a gate connection line.

[0011] Furthermore, the ITO strips corresponding to the signal connection lines are first-type ITO strips, and the ITO strips corresponding to the gate connection lines are second-type ITO strips.

[0012] Furthermore, the second type of ITO strips and the first type of ITO strips are of the same type.

[0013] Furthermore, a group of gate connection lines are respectively arranged on both sides of the non-display area.

[0014] Furthermore, the display screen body is also provided with FPC electrodes.

[0015] The TFT liquid crystal display screen of the present application no longer uses a whole piece of ITO, but uses an ITO strip on each connecting line, thereby greatly reducing the area of ​​ITO, reducing the probability of static electricity generation, and further reducing the impact of static electricity on the TFT liquid crystal display screen.

[0016] Other features and advantages of the present application will be set forth in the following description, and in part will become apparent from the description, or may be understood by practicing the present application. BRIEF DESCRIPTION OF THE DRAWINGS
