Title:
SPLIT TYPE TFT ELEMENT STRUCTURE FOR LARGE SCREEN DISPLAY, AND DEFECTIVE TFT TREATMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/124489
Kind Code:
A1
Abstract:
The present invention relates to a split type TFT element structure for a large screen display, and a defective TFT treatment method therefor. In the designing of pixels of a large screen display, the present invention splits a TFT constituting a pixel into a plurality of unit TFTs, interconnects the same in parallel, and releases the parallel connection of only the corresponding TFT in which a defect has occurred, thereby enabling the corresponding TFT to be prevented from becoming a defective pixel, when a unit TFT in which a defect has occurred exists among the unit TFTs. Therefore, in the designing of pixels of a large screen display, yield reduction caused by defective pixels can be alleviated.
