Among them, the plurality of data lines 20 are arranged neatly, the plurality of scan lines 30 are arranged parallel to each other, the plurality of data lines 20 and the plurality of scan lines 30 are arranged perpendicular to each other, and pixels are provided at each intersection of the plurality of data lines 20 and the plurality of scan lines 30.

[0023] Referring to Figure 1 , the number of the data lines 20 is set according to the resolution of the display screen 10, and the data lines 20 provide data signals for the pixels displayed on the display screen 10. The scan lines 30 are used to provide scan signals for the pixels displayed on the display screen 10.

[0024] Referring to Figure 1 , the display screen 10 further includes a data line driving circuit and a scan line driving circuit, and the plurality of data lines 20 are all connected to the data line driving circuit, and the plurality of scan lines 30 are all connected to the scan line driving circuit.

[0025] Referring to Figure 1 , the display screen 10 further includes a plurality of TFT switches 40, each data line 20 and each scan line 30 are connected to the TFT switch 40, and the TFT switch 40 is respectively connected to the data line 20 and the scan line 30 adjacent to this data line 20. The data line 20 and the scan line 30 are respectively connected to the data line driving circuit and the scan line driving circuit through the TFT switch 40, and the TFT switch 40 can control the opening and closing of the data line 20 and the scan line 30 connected thereto to control the display of pixels.

[0026] Referring to Figure 1 , because there are many uncontrollable factors in the manufacturing process of the display screen 10 that may cause product scrapping, such as the breakage of one or several data lines 20 due to static electricity, dust, exposure, scratching, etc., resulting in circuit failure and becoming defective products. Therefore, protection lines 50 are provided at multiple data lines 20, the protection lines 50 overlap with the data lines 20, and the protection lines 50 are used to protect the data lines 20 from being scratched in subsequent processes, reducing the resistance of the data lines 20 and effectively improving the yield of the display screen 10 at the same time.

[0027] Referring to Figure 1 , the protection line 50 is a PITO metal line, and the PITO metal line is an ITO line used as a pixel electrode. The protection line 50 overlaps on the data line 20, so that the protection line 50 can protect the data line 20, and the protection line 50 is not connected to adjacent traces, that is, adjacent protection lines 50 do not contact.

[0028] Referring to Figure 1 , a protection line 50 is provided at each data line 20 on the display screen 10, and the plurality of data lines 20 are respectively overlapped with the plurality of protection lines 50.

[0029] Referring to Figure 1 , a driving IC 60 is provided on the display screen 10. The driving IC 60 is used to control the display of the display screen 10. A plurality of data lines 20 and a plurality of scanning lines 30 are both connected to the driving IC 60, and the driving IC 60 is connected to a plurality of TFT switches 40, a data line driving circuit, and a scanning line driving circuit. Thus, the TFT switches 40, the data line driving circuit, and the scanning line driving circuit can be controlled to realize the display control of the pixels of the display screen 10.

[0030] Further, referring to Figure 1 , a plurality of protection lines 50 are lapped on the regions of the plurality of data lines 20 close to the connection with the driving IC 60. The region where the data line 20 is connected to the driving IC 60 is liable to break due to various reasons, resulting in the disconnection between the data line 20 and the driving IC 60. Therefore, the protection line 50 is lapped on the region of the data line 20 close to the connection with the driving IC 60 to protect the data line 20.
