Abstract
An OLED display device includes multiple pixel units arranged in a matrix and a power supply driver chip located at one side of the multiple pixel units. The power supply driver chip is configured to supply input voltages to the multiple pixel units. The power supply driver chip provides the input voltages to the multiple pixel units through a plurality of input paths. The input paths are associated with input points, each of the input points corresponds to a pixel unit at a different location. The power supply driver chip compensates the input voltages to ensure that all of the pixel units at different locations may have an approximately equal input voltage, enabling the entire display region of the OLED display device to display with a uniform brightness and improving the display performance.
