MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617091152 A) filed by Boe Technology Group Co. , Ltd. on July 27, 2026, for Pixel Circuit And Driving Method Therefor, Display Substrate, And Display Apparatus.
Inventors include Zhu, Jianchao; Zhao, Xuliang; Liu, Libin; Hu, Ming; and Huangfu, Lujiang.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A pixel circuit, comprising: a drive sub-circuit (11), a data writing sub-circuit (13), a compensation sub-circuit (12), a coupling sub-circuit (14) and a first control sub- circuit (15). The coupling sub-circuit (14) is coupled to a first node (N1) and a third node (N3). The first control sub-circuit (15) is configured to write a first reference voltage signal, which is provided by a first reference voltage line (REF1), into the third node (N3) under the control of a first control line (S1) after the data writing sub- circuit (13) writes a data signal to the third node (N3), such that the data signal is coupled to the first node (N1) by means of the coupling sub-circuit (14).
