Latest Patents
One of JinCheol Hong's latest patents is a display device that optimizes the power control signal of a source driver integrated circuit to enhance power consumption efficiency. This innovative display device includes a display panel with sub pixels that emit light in various colors. It features a data driver that outputs a data voltage to the sub pixels through data lines, along with a timing controller that generates power control signals to manage the driving current for the data driver. The data driver comprises source driving integrated circuits, which include power control circuits that produce the driving current based on the power control signals, and amplifiers that apply the driving current to output the data voltage to the data lines.
Another notable patent is related to a display device and its driving method. In this invention, during an optimization mode, the controller sends a first lock signal with pulse waveforms to a first source driver circuit. It then receives a second lock signal with pulse waveforms from the last source driver circuit that received the first lock signal. The controller transmits phase loop fixed data to recover the frequency and phase of a clock to each source driver circuit upon receiving the second lock signal. In display mode, the controller sends a first lock signal with a preset voltage level to the first source driver circuit and receives a second lock signal with multiple preset voltage levels from the last source driver circuit. It supplies image signals and control data to each source driver circuit when the second lock signal is received.
