MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202527113632 A) filed by Tcl China Star Optoelectronics Technology Co. , Ltd. on November 19, 2025, for Display Apparatus And Drive Method Therefor.
Inventors include Wu, Xiaoling; Wang, Tianhong; and Yao, Jiangbo.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: A display apparatus (100) and a drive method therefor. In a pixel circuit (20) of the display apparatus (100), a data writing transistor (T2) first transmits to a gate electrode of a drive transistor (T1) a first reset signal (Vini) generated by a voltage generation unit (102); a compensation transistor (T4) is turned on; the drive transistor (T1) then receives a first voltage signal (Vdd), and the drive transistor (T1) is turned on, such that the potential (Vg) at the gate electrode of the drive transistor (T1) rises or falls until the drive transistor (T1) is turned off; and a measurement unit (101) then acquires the potential (Vg) at the gate electrode of the drive transistor (T1) by means of the data writing transistor (T2), so as to generate a compensation voltage signal (Vb).
