Abstract: A pixel driving circuit for a light-emission-device-based display panel is provided, including a driving transistor coupled to a light-emission device per subpixel; a digital-driving circuit having a first input terminal configured to receive a pixel voltage signal corresponding to a grayscale level of a subpixel image to be displayed and a first output terminal coupled to a gate terminal of the driving transistor. The digital-driving circuit is configured to convert the pixel voltage signal to a digital signal and transform the digital signal to a pulse-width-modulation (PWM) signal outputted via the first output terminal to the gate terminal of the driving transistor. The PWM signal comprises a pulse width proportional to the grayscale level as a duty cycle in a period of driving the light-emitting device to display subpixel image.

Abstract: A method for processing image data with reduced transmission bandwidth is provided. The method includes receiving a first set of data for image in a first resolution and receiving a center coordinate. The method further includes determining a high-definition region including an area and a boundary centered on the center coordinate. Additionally, the method includes rendering the first set of data based on the center coordinate and the area of the high-definition region to obtain a first subset of data. Furthermore, the method includes rendering a set of data compressed from the first set of data to obtain a second subset of data beyond the boundary. Moreover, the method includes transmitting a second set of image data to the display panel combining the first subset of data for display image in the first resolution and the second subset of data to display image in the second resolution.

Abstract: The present disclosure describes a data transmission method, a timing controller, a source driver, and a data transmission system. The method includes: when the timing controller transmits data to the source driver at a speed n times a preset speed, the timing controller suspends transmission of valid data with the source driver after completing transmission of a first data packet; and the transmission of valid data with the source driver is resumed at a transmitting time of a second data packet; the first data packet and the second data packet each includes valid data of a row of sub-pixels, or each includes valid data of a frame. The present disclosure completes the transmission of the first data packet in advance by increasing the transmission speed, then suspends the data transmission, and resumes the data transmission at the transmitting time of the second data packet, thereby reducing the power consumption.
