    摘要: The present disclosure provides a display substrate and a display device. The display substrate includes a plurality of sub-pixels in rows. The sub-pixels in each row includes first sub-pixels, second sub-pixels and third sub-pixels arranged alternately, and two adjacent rows of sub-pixels are arranged in a staggered manner. In every two adjacent rows of sub-pixels, each first sub-pixel in one row of sub-pixels and the second sub-pixel and the third sub-pixel adjacent to the first sub-pixel in another row of sub-pixels form a pixel. White brightness centers of the pixels in a same pixel row are located on a same straight line, and a brightness center of the first sub-pixel is not on a same straight line as the brightness centers of the second sub-pixel and the third sub-pixel located in a same sub-pixel row.

    摘要: A control circuit, a testing apparatus and a method for testing a liquid crystal display panel are provided. The control circuit includes a current sensor and a discharge signal generation circuit. The current sensor is configured to detect a change in an input current of the liquid crystal display panel to generate an indication signal, the indication signal being indicative of switching of image frames displayed by the liquid crystal display panel. The discharge signal generation circuit is configured to receive the indication signal from the current sensor, and the discharge signal generation circuit generates a discharge signal in response to receiving the indication signal, so that a liquid crystal capacitor including the common electrode and the pixel electrode in the liquid crystal display panel is discharged. Hence, the quality of images displayed by the liquid crystal display panel can be improved and the product yield can be increased.
