Technical Field

The invention relates to a design method of a display panel of a portable electronic device.

Background

With the rapid development of portable electronic devices, the requirements of display panels are gradually increasing, especially the requirements for miniaturization, low power consumption, low cost, high image quality, and the like are increasing.

Fig. 1 is a schematic structural diagram of a display panel of a portable electronic device in the prior art, the display panel is an amorphous silicon (α -Si) panel, and includes a substrate glass 10, a driving chip 40, and a flexible circuit board 50, wherein the substrate glass 10 includes a display area 20 and a non-display area 30, and the driving chip 40 is disposed in the non-display area 30 of the substrate glass 10.

The source driving signal pin and/or the touch panel signal pin 41 of the driving chip 40 are located at a side close to the display area 20, and the height of the non-display area occupied by the connection line of the source driving signal pin and/or the touch panel signal pin 41 and the display area 20 is D31. The input/output pins 42 of the driving chip 40 are disposed on a side of the driving chip 40 away from the display area 20, the electrical connection points 43 of the flexible circuit board 50 and the substrate glass 10 are disposed below the driving chip 40, and a connection line between the input/output pins 42 and the electrical connection points 43 occupies a non-display area with a height D33. The height of the driver chip 40 itself is D32. Therefore, the overall height D30 of the non-display region is at least D31+ D32+ D33, typically around 4.2 mm. With the increasing demand for the portability of electronic devices and the increasing demand for the integration level of display panels, in order to ensure the image quality, the size of the display area is generally increased, and therefore, how to effectively reduce the size of the non-display area, especially the overall height D30 of the non-display area, is a technical problem that needs to be solved at present.

A method of disposing a driving chip on a separate thin film on a low temperature poly-silicon (LTPS) display panel and then connecting the driving chip to a flexible circuit board has been proposed, and since the driving chip is not required to be disposed on a non-display region of a glass substrate, the height of the non-display region of the glass substrate can be greatly reduced, but the method is not suitable for an amorphous silicon panel and requires a Multiplexer (MUX) to reduce the number of wires, and in addition, the cost of the thin film is high, so that the manufacturing cost of the display panel is significantly increased.
