Problems solved by technology
[0003] Because the fingerprint function is embedded in the panel AA area (Active Area, operable area) and other reasons, there are some special-shaped areas in the AA area. Because the shape of these special-shaped areas is different from the main body of the AA area, the signal caused by the impedance of the scanning line in it The delay is different from the main body of the AA area, which causes the display effect of the special-shaped area to be different from that of the main body of the AA area, that is, a split screen phenomenon occurs
[0004] The existing improvement method is to change the conventional cross-driving method to double-sided driving, which can eliminate the impedance difference caused by the different lengths of the scanning lines, but the traditional double-sided driving structure is complicated, which will cause the left and right edges of the display panel to increase

The invention discloses an array substrate and a display panel. The array substrate comprises multiple scanning lines which include first scanning lines and second scanning lines; a first scanning circuit which includes multiple scanning units, wherein the scanning units are electrically connected with the first end of the second scanning lines; a control circuit which includes multiple control units and is electrically connected with the first scanning lines and the second scanning lines. The control units are in the first conduction state in the first time and the scanning units input an effective scanning signal to the first scanning lines via the second scanning lines. The control units are in the second conduction state in the second time, the scanning units input the effective scanning signal to the second scanning lines and the control units input an ineffective scanning signal to the first scanning lines. The number of the scanning units in the array substrate can be reduced.
Description
Technical field [0001] The present invention relates to the field of display technology, and more specifically, to an array substrate and a display panel. Background technique [0002] The current mobile phone display architecture has changed from the early low-screen-to-body ratio to the high-screen ratio. In order to achieve a high-screen-to-body ratio, the fingerprint recognition module is integrated into the display area and the notch structure for the camera and earpiece is reserved, which has become a high-end The trend of mobile phone displays. [0003] Because the fingerprint function is embedded in the AA area (Active Area, operable area) of the panel, etc., there are some special-shaped areas in the AA area. These special-shaped areas are different from the main body of the AA area, resulting in signals caused by the impedance of the scan line inside. The delay is different from the main body of the AA area, so that the display effect of the special-shaped area is differ...
