Latest Patents

One of his latest patents is for a flexible display device and method for detecting the bending state thereof. This invention involves an organic EL panel that is a bendable display panel, which includes a plurality of pixel circuits, each having a light-emitting element and a drive element. The data line drive circuit plays a crucial role by driving data lines to write a voltage to the control terminal of the drive element and measuring the current flowing through the drive element for the selected pixel circuits. A bending detection unit is integrated to detect the bending state of the organic EL panel based on the measurement results. This innovation prevents changes in brightness or color when the screen is bent.

Another notable patent is focused on a pixel circuit, display device, and method for driving the same. The purpose of this invention is to suppress voltage fluctuations that occur when an analog voltage signal is sampled and held in a data line within a display device equipped with a current-driven display element. The design includes transistors that are successively switched on during a predetermined selection period, ensuring that the voltage held by the data line is compensated for, thus maintaining display quality.
