Referring to fig. 4, in manufacturing the display panel provided by the embodiment of the present disclosure, two bottom gate electrodes 005 may be formed first, and then a semiconductor layer 006 may be formed on each bottom gate electrode; next, a gate layer is formed over the bottom gate electrode where the semiconductor layer 006 is formed; and then, performing a patterning process (the patterning process includes steps of coating, exposing, developing, etching, and the like) on the gate layer to form the gate line as shown in fig. 4. In addition, the gate line layer may be subjected to a patterning process once to form the gate line as shown in fig. 6.

Referring to fig. 4, the working process of the display screen provided by the embodiment of the present disclosure may be:

1) the driver IC001 acquires a local display signal and a clock signal (english: clock). The local display signal is used for indicating a target grid line which is turned on or off in the n grid lines during image display, and the target area of the image display corresponding to the local display signal is smaller than the area of the display screen. For example, when a user wants to view time through the display device, the user may click the floating button corresponding to the time, the user generates a display instruction in a process of clicking the floating button corresponding to the time, the driving IC001 receives the display instruction triggered by the user, detects that the display instruction is triggered by a preset local display mode, the driving IC001 determines to perform local display, and the driving IC001 generates a local display signal, where the local display signal is used to indicate a target gate line that is opened or closed in n gate lines during time image display. For another example, when a user wants to view a short message through the display device, the user may click the hover button corresponding to the short message, the user generates a display instruction in the process of clicking the hover button corresponding to the short message, the driver IC001 receives the display instruction triggered by the user, detects that the display instruction is triggered by a preset local display mode, the driver IC001 determines to perform local display, the driver IC001 generates a local display signal, and the local display signal is used to indicate a target gate line that is opened or closed in n gate lines when displaying a short message image. For another example, when a user wants to enable the display device to enter a standby state, the user may click the standby button, the user generates a display instruction in the process of clicking the standby button, the driving IC001 receives the display instruction triggered by the user, detects that the display instruction is triggered by a preset local display mode, the driving IC001 determines to perform local display, and the driving IC001 generates a local display signal, where the local display signal is used to indicate a target gate line that is turned on or off in n gate lines when a standby image (e.g., a screen saver image) is displayed.

It should be added that, the display screen may receive a display instruction triggered by a user through the driving IC001, determine whether to perform local display according to the display instruction, and generate a local display signal when determining to perform local display; or receiving a display instruction triggered by a user through a processing module of the display device, such as a CPU (central processing unit), determining whether to perform local display according to the display instruction, generating a local display signal when determining to perform local display, and sending the local display signal to the driving IC 001; or receiving a display instruction triggered by a user through a processing module of the display device, such as an instruction recognition IC, determining whether to perform local display according to the display instruction, generating a local display signal when determining to perform local display, and sending the local display signal to the driving IC 001.

2) The driving IC001 controls the time of turning on each gate line by the GOA switch 002 according to the clock signal, determines the control voltage corresponding to each gate line 003 according to the local display signal, outputs the control voltage corresponding to the gate line to the switch unit corresponding to the gate line at the turn-on time of the gate line 003, and controls the turn-on or turn-off of the gate line 003. Specifically, the driving IC001 is electrically connected to each semiconductor layer 006 through the bottom gate 005, and the output control voltage controls the semiconductor layer 006 to be conductive or non-conductive. When the output control voltage is the turn-on voltage, the semiconductor layer 006 becomes a conductor, and the gate line on the semiconductor layer 006 is turned on by the semiconductor layer 006 and the GOA switch 002; when the output control voltage is an off voltage, the semiconductor layer 006 becomes an insulator, and the gate line on the semiconductor layer 006 is turned off by the semiconductor layer 006. The magnitude of the turn-on voltage can refer to the magnitude of the turn-on voltage of a grid line preset on a screen of the display screen, and the magnitude of the turn-off voltage can refer to the magnitude of the turn-off voltage of the grid line preset on the screen of the display screen.

If the local display signal indicates that a target gate line that is turned on or off among N gate lines during image display should be turned on in fig. 4, and the time for the GOA switch 002 to turn on the nth gate line is 333 microseconds to 498 microseconds, then at the turn-on time of the nth gate line, that is, at 333 microseconds, the driving IC001 outputs a control voltage, that is, a turn-on voltage, corresponding to the nth gate line to the switching unit corresponding to the nth gate line, at this time, the semiconductor layer 006 becomes a conductor, and the nth gate line is turned on. Assuming that there are 100 gate lines in fig. 4, and the time for the GOA switch to open each gate line is 1/(60 × 100) sec, which is 166 microseconds, the corresponding relationship between 100 gate lines and the time for the GOA switch to open each gate line can be shown in table 1, and the direction of the gate lines opened by the GOA switch can be known, where the 1 st gate line in table 1 is the 1 st gate line from top to bottom in fig. 4, the 2 nd gate line in table 1 is the 2 nd gate line from top to bottom in fig. 4, and the rest of the gate lines in table 1 are analogized in sequence. As can be seen from table 1, the time for the GOA switch to turn on the 3 rd gate line is 333 microseconds to 498 microseconds, and when the 3 rd gate line needs to be turned on, the driving IC001 needs to output a turn-on voltage to the switch unit corresponding to the 3 rd gate line at 333 microseconds.

TABLE 1

100 grid lines	Time for GOA switch to open each grid line
		No. 1 grid line	1 st microsecond to 166 th microsecond
No. 2 grid line	167 th microsecond to 332 th microsecond
		The 3 rd grid line	333 rd microsecond to 498 th microsecond
…	…
		The 100 th grid line	16435 th microsecond to 16600 th microsecond

Taking fig. 4 and table 1 as an example, when a user wants to check weather through the display device, the user operates the display device to generate a display instruction, the driver IC001 receives the display instruction triggered by the user, and the driver IC001 determines to perform the display operation according to the display instructionAnd displaying locally, the driving IC001 acquires content in the weather image indicated by the display instruction, and divides the weather image into a display area and a non-display area according to the content, assuming that 100 grid lines are provided, the display area may correspond to 96 grid lines (3 rd to 98 th grid lines), the non-display area may correspond to 4 grid lines (such as 1 st grid line, 2 nd grid line, 99 th grid line, and 100 th grid line), and the driving IC001 regenerates a local display signal indicating that, when displaying the weather image, the 3 rd to 98 th grid lines corresponding to the display area among the 100 grid lines are turned on, and the 1 st grid line, the 2 nd grid line, the 99 th grid line, and the 100 th grid line corresponding to the non-display area are turned off. Then, when the gate line 3 is turned on by the GOA switch, that is, at 333 microseconds, the driving IC001 outputs an on voltage to the switching unit corresponding to the gate line 3, at this time, the semiconductor layer 006 of the switching unit becomes a conductor, the gate line 3 is turned on, when the gate line 4 is turned on by the GOA switch, the driving IC001 outputs an on voltage to the switching unit corresponding to the gate line 4, the gate line 4 is also turned on, and similarly, the gate lines 5 to 98 are also turned on in sequence, when the gate line 99 is turned on by the GOA switch, the driving IC001 outputs an off voltage to the switching unit corresponding to the gate line 99, at this time, the semiconductor layer 006 becomes an insulator, the gate line 99 is turned off, and similarly, the gate line 100 is also turned off. Fig. 7-1 and 7-2 show a voltage signal waveform diagram of a gate line and a voltage signal waveform diagram of a bottom gate corresponding to the control process, where fig. 7-1 is a schematic diagram of a turn-on period of the gate line included in the first gate line group in fig. 4 and a voltage waveform diagram of the bottom gate corresponding to the first gate line group, the turn-on period of the gate line is a period when the gate line is turned on by the GOA switch, fig. 7-2 is a schematic diagram of a turn-on period of the gate line included in the second gate line group in fig. 4 and a voltage waveform diagram of the bottom gate corresponding to the second gate line group, and the turn-on period of the gate line is a period when the gate line is. V1 denotes an ON voltage, v2 denotes an OFF voltage, and t 2 denotes an ON voltage in FIGS. 7-1 and 7-2_oIndicating the period of time that the gate line is turned on by the GOA switch. As shown in fig. 7-1 and 7-2, the control voltage corresponding to the gate line is outputted to the switching unit corresponding to the gate line at the turn-on time of the gate line to control the bottom gate voltage and filter out the gate line that does not need to be turned onAnd (4) passing the signals of the grid lines needing to be opened, and finally realizing local display. It should be added that the display screen may control the on/off of the continuous gate lines, such as controlling the 3 rd to 98 th gate lines mentioned in the above control process, or may control the on/off of the discontinuous gate lines, such as controlling the on/off of the 3 rd, 5 th, and 7 th gate lines, and controlling the off/on of the 4 th and 6 th gate lines, and the control process may refer to the above control process, which is not described herein again.
