Title:
DISPLAY PANEL AND DRIVE SUBSTRATE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/040843
Kind Code:
A1
Abstract:
The present application provides a display panel (100) and a drivr substrate (1) thereof. The drive substrate (1) is used for driving an inorganic light-emitting diode to emit light. The drive substrate (1) comprises a substrate (11) as well as a first insulating layer (122), an active layer (123), and an electrode layer (125) which are sequentially arranged on the substrate (11). The electrode layer (125) comprises a source electrode (1251) and a drain electrode (1252) which are arranged in the same layer. A light shielding portion is further comprised. The light shielding portion (13) is located between the electrode layer (125) and the substrate (11) and at least partially overlaps with the electrode layer (125). The light shielding portion (13) is spaced apart from the active layer (123) and penetrates the first insulating layer (122); and/or the light shielding portion (13) is at least partially located on the side of the electrode layer (125) away from the substrate (11) and covers the active layer (123). By means of arranging the light shielding portion (13) around the active layer (123) to shield from light emitted towards the active layer (123), the active layer (123) in the drive substrate (1) is prevented from being illuminated and thus causing changes in the characteristics of a thin film transistor (12).
