Latest Patents
One of his latest patents is an AMOLED display driving device with a switching frame rate. This device allows for the display to be switchable among multiple frame rates. It includes a timing control unit, a panel driving unit, and an emission duty ratio control unit. The timing control unit adjusts the display time and V-blanking time based on the input frame rate, ensuring that the display time aligns with a standard display time. The panel driving unit then drives the AMOLED display panel to present the input frame according to the modified display parameters. Additionally, the emission duty ratio control unit applies multiple emission pulses to the AMOLED display panel during the frame period.
Another significant patent is a filtering film structure. This structure consists of a film, a conductive layer, and a dielectric layer. The film features numerous holes, with the conductive layer positioned on the inner surface of these holes. The dielectric layer is placed on top of the conductive layer. When a voltage is applied to the conductive layer, an electrical charge layer forms on the dielectric layer's surface, enhancing its functionality.
