Embodiment Construction

[0042]Please refer to FIG. 4 , which is a schematic diagram of an ESD protection circuit 50 used to protect a main circuit 60 according to a preferred embodiment of the present invention. As shown in FIG. 4 , the ESD protection circuit 50 includes a plurality of first thin film diode assemblies 52 coupled in series and a plurality of second thin film diode assemblies 54 coupled in series. In this embodiment, the main circuit 60 may be a display circuit of an LCD panel or a display circuit of an OLED panel. In addition, the first thin film diode element 52 and the second thin film diode element 54 are formed on the substrate of the display panel by thin film technology and injection technology.

[0043] The first thin film diode assembly 52 is coupled in series with each other, and one end of the first thin film diode assembly 52 is electrically connected to a position on the signal line 56 between the input end 58 and the main circuit 60 of the display panel, wherein the signa...

Abstract

Systems for providing electrostatic discharge (ESD) protection. One of the Systems has a plurality of first-type thin film diode elements coupled to each other in series, and a plurality of second-type thin film diode elements coupled to each other in series. The first-type thin film elements are electrically connected to a signal line between an input end and a main circuit, and the second-type thin film diode elements are electrically connected to the signal line between the input end and the main circuit.

Description

technical field [0001] The invention relates to an electrostatic protection system, in particular to an electrostatic protection system capable of preventing electronic devices from being damaged by static electricity. Background technique [0002] ESD damage to integrated circuits is a thorny issue for a wide variety of electronic products. Taking a liquid crystal display panel as an example, the liquid crystal display panel usually includes two glass substrates made of non-conductive material. Since the sudden static electricity cannot be conducted to the outside through the non-conductive glass substrate, the energy carried by the static electricity will cause damage to the devices on the glass substrate. Therefore, in order to prevent the device from being damaged by static electricity, a static electricity protection system is usually provided in the liquid crystal display panel. [0003] Please refer to FIG. 1 , which is a schematic diagram of an ESD protection circu...
