Abstract: Embodiments of the present disclosure provide an OLED display panel and a driving method thereof. The OLED display panel includes a plurality of power lines, each power line connecting to a plurality of pixels, and one end of each power line connecting to a power source. The method includes acquiring a current value of the power line and comparing it to a preset threshold, when a current value of the power line is less than or equal to the threshold, providing an original data voltage to the pixels connected to the power line, when a current value of a power line is greater than the threshold, providing a compensating data voltage to the pixel connected to the power line. The compensating data voltage is equal to the difference between the original data voltage and the compensation voltage.

Abstract: A virtual provider edge server may include different modules that implement a hybrid provider edge. A flow detection module may sample received traffic through a server and adaptively detect flows to be offloaded. An offloading module may be an SDN controller that controls the flow tables of a switch that data traffic is offloaded to.

Abstract: The present disclosure provides a gamma tuning method and a gamma tuning device. The gamma tuning method includes steps of: comparing grayscale binding points of a to-be-debugged module with a standard gamma curve; determining a to-be-tuned grayscale binding point from the grayscale binding points of the to-be-debugged module in accordance with a comparison result between the grayscale binding points of the to-be-debugged module and the standard gamma curve; and tuning a grayscale brightness value of the to-be-tuned grayscale binding point in accordance with a target brightness value of the grayscale binding point on the standard gamma curve.

Abstract: Embodiments of the present disclosure provide gamma correction method and device for a display module. The gamma correction method includes: determining, for each sub-pixel of a display module to be corrected, the highest data voltage and the lowest data voltage after gamma correction of the highest gray scale and the lowest gray scale of the display module; determining at least one set of alternative gamma register values that are capable of performing gamma correction of the display module; determining at least one set of gamma register values to be corrected for respective gray scales before the gamma correction of the display module; and performing gamma correction of the display module by adjusting the gamma register value corresponding to the gray scale to be corrected which needs to perform gamma correction.
