Latest Patents

One of Weonjun Choe's latest patents is a data compensating circuit and display device that includes a stress data generating block. This block generates stress data for each pixel based on input or output image data. The invention also features a memory control block that updates accumulated stress data for each pixel. Additionally, a first compensating block reads this accumulated stress data from a non-volatile memory device to generate afterimage compensation data. The compensation data summing block then combines this data with optical compensation data to produce luminance compensation data for each pixel. The second compensating block ultimately generates output image data by compensating for the input image data based on the luminance compensation data.

Another notable patent is a display device that comprises a display panel with pixels and a driving controller. This controller receives an image signal and outputs a compensated image data signal. It includes a memory and a hysteresis calculator that calculates the current hysteresis state value based on the image signal and a previous state value stored in memory. The compensator then calculates a compensation value to adjust the image signal accordingly.
