Abstract

A display panel and a manufacturing method thereof are disclosed herein. The display panel includes a substrate, a peripheral circuit, a plurality of pixel electrodes, a plurality of switches, and an insulating layer. The substrate has a display region and a non-display region. At least a portion of the peripheral circuit is located on the display region of the substrate. The pixel electrodes are located on the display region of the substrate. The switches are respectively and electrically connected to the pixel electrodes, configured to be respectively switched on according to a plurality of scan signals, so as to transmit a plurality of data signals to the pixel electrodes. The insulating layer is located between the peripheral circuit and the pixel electrodes, and is configured to prevent the peripheral circuit from interfering with the pixel electrodes.

Claims (18)

1. A display panel comprising:

a substrate comprising a display region and a non-display region;

a peripheral circuit, wherein at least a portion of the peripheral circuit is located on the display region;

a plurality of pixel electrodes located on the display region;

a plurality of switches respectively and electrically connected to the pixel electrodes, wherein the switches are configured to be switched on according to a plurality of scan signals respectively, so as to transmit a plurality of data signals to the pixel electrodes; and

an insulating layer located between the peripheral circuit and the pixel electrodes, wherein the insulating layer is configured to prevent the peripheral circuit from interfering with the pixel electrodes;

wherein the peripheral circuit comprises a shorting bar line, at least a portion of the shorting bar line is located on the display region, and the shorting bar line is configured to receive a test signal and to provide the test signal to at least one of the switches to thereby perform testing of the display panel.

2. The display panel as claimed in claim 1 further comprising:

a display layer configured to display an image according to the data signals received by the pixel electrodes.

3. The display panel as claimed in claim 1 , wherein the peripheral circuit comprises an amorphous silicon array driver (ARD), at least a portion of the ARD is located on the display region, and the ARD is configured to provide the scan signals to the switches.

4. The display panel as claimed in claim 3 further comprising:

a display layer configured to display an image according to the data signals received by the pixel electrodes.

5. The display panel as claimed in claim 1 , wherein the peripheral circuit comprises an electrostatic discharge (ESD) protection circuit, at least a portion of the ESD protection circuit is located on the display region, and the ESD protection circuit is configured to electrically connect to a scan line or a data line, so as to prevent the display panel from being damaged by electrostatic discharge.

6. The display panel as claimed in claim 5 further comprising:

a display layer configured to display an image according to the data signals received by the pixel electrodes.

7. The display panel as claimed in claim 1 further comprising:

a display layer configured to display an image according to the data signals received by the pixel electrodes.

8. The display panel as claimed in claim 1 , wherein a thickness of a portion of the insulating layer interposed between the peripheral circuit and the pixel electrodes is greater than 15 kÅ.
