LTPS display panel and making process thereof

Abstract

The invention discloses an LTPS display panel and a making process thereof. The LTPS display panel comprises a color filter, a black matrix located on the color filter and a TFT substrate which is located on one side of the black matrix and arranged opposite to the color filter. A conducting ring is arranged on the color filter and located on the outer side of the black matrix. A partition groove is formed between the conducting ring and the black matrix. One or more ground pins are arranged on the TFT substrate. The conducting ring on the color filter is electrically connected with the ground pins on the TFT substrate to form an ESD discharge path. Static electricity formed at the edge of the panel can be released to the ground through the ESD discharge path, then poor ESD display caused by a chip gap formed due to cutting of the panel can be prevented, and ESD reliability of the panel is improved.

Description

technical field [0001] The invention relates to the technical field of LTPS display, in particular to an LTPS display panel and a preparation process thereof. Background technique [0002] With the continuous improvement of low temperature polysilicon (LTPS, Low Temperature PolySilicon) equipment and process technology, more and more panel manufacturers have gradually invested a lot of energy and cost in the field of low temperature polysilicon technology. The low-temperature polysilicon manufacturing process can enable display panels to have higher pixel density (PPI) and narrower borders, all of which benefit from the large electron mobility of low-temperature polysilicon. [0003] In the terminal display market, especially the smart phone market, companies are looking for product differentiation or product innovation to take advantage of the opportunity to promote the selling points of new mobile phones. At present, narrow borders or even "no borders" have always been a ...
