Abstract

The invention provides a driving circuit, a display screen and a display device of a display panel with a groove, wherein, the driving circuit comprises a first type driving line for adjusting the luminance of pixels of a row or column in which the groove is located, and / or for adjusting the luminance of pixels of a row or column adjacent to the groove, and a driving line for adjusting the luminance of the pixels of the row or column. A second type of drive line for adjusting the gate voltage of the data writing circuit; A current or voltage applied to the first type of drive line is differentfrom that applied to the second type of drive line. The above drive circuit, A light-emitting brightness of pixel of a row or column in which a groove is located and / or a row or column adjacent to that groove is adjust using a drive line of a first type, A second type of driving line adjusts the luminance of pixels in other rows or columns, and a first type of driving line adjusts the luminance of pixels in the groove separately, so that the luminance of the entire display panel with the groove is consistent, the uniformity of the display is improved, and the mura problem caused by the grooveis avoided. The second type of driving line adjusts the luminance of pixels in other rows or columns, and the first type of driving line adjusts the luminance of pixels in the groove separately.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving circuit of a display panel with grooves, a display screen and a display device. Background technique [0002] With the development of OLED display screens, the application fields are becoming wider and wider, and the forms of the screen body are also tending to be diversified. The slotted design is a new technology that can achieve a higher screen-to-body ratio while also avoiding some functional components. However, the notch design leads to a more serious defect of uneven brightness (mura) of the display screen. Contents of the invention [0003] Based on this, it is necessary to provide a drive circuit, a display screen and a display device for a display panel with grooves to avoid the mura defect caused by the grooves. [0004] For this reason, the present invention provides following technical scheme: [0005] According to the first aspect of the present inve...
