Each pixel unit comprises a switch element with an active layer, and the vertical projection of the active layer of each pixel unit on the substrate completely falls into the vertical projection of one shielding unit on the substrate. The first to sixth pixel units arranged in sequence in the same column are respectively provided with first to sixth shielding units. The first shielding unit is electrically connected with the fourth shielding unit, the second shielding unit is electrically connected with the fifth shielding unit, and the third shielding unit is electrically connected with the sixth shielding unit.

This application discloses a brightness adjustment method, a display device, and a computer-readable storage medium. The brightness adjustment method includes controlling the display panel to enter a partial brightness mode after receiving a target instruction instructing the display panel to enter a partial brightness mode; after the display panel enters the partial brightness mode, if the target brightness value of a second area in the displayed image is less than a preset inflection point brightness value, the brightness value of the second area in the display panel is first adjusted to the inflection point brightness value using a brightness level; then, the brightness of the second area in a first image is adjusted using a first calibration value, and the brightness of the second area in a second image is adjusted to the target brightness value using a second calibration value; wherein the first image and the second image are both displayed images after the display panel enters the partial brightness mode, and the first image is positioned before the second image. This solution can improve the problem of unstable display brightness after the display panel enters the partial brightness mode.

The invention discloses a pixel circuit, a driving method thereof and a display panel, and belongs to the technical field of display. The pixel circuit comprises a driving module, a threshold compensation module and an initialization module. The first end of the driving module accesses a first power signal, and the second end of the driving module is connected with the anode of the light-emitting device. The threshold compensation module is connected between the control end and the first end of the driving module, and a first scanning signal is accessed; the initialization module is connected with the anode of the light-emitting device, and accesses a first scanning signal, a second scanning signal and an initialization signal; the initialization module is used for responding to the effective potential of the first scanning signal and / or the effective potential of the second scanning signal and transmitting an initialization signal to the anode of the light-emitting device; wherein the second scanning signal has a first frequency, the refresh frequency of the pixel circuit is smaller than or equal to the first frequency, and the frequency of the first scanning signal is equal to the refresh frequency. According to the embodiment of the invention, the display effect of the display panel under low refresh frequency can be improved.

This disclosure provides a display screen and its driving method and display system, relating to the field of display technology. The display screen includes a display area, a scanning module, and a driving module. The display area includes multiple rows of sequentially arranged light-emitting elements. The scanning module scans the rows of light-emitting elements according to a preset rule within a scanning cycle. The preset rule is that there is an interval of 'a' rows between the Nth scanned row and the (N+1)th scanned row, where N is an integer greater than or equal to 1, and a is an integer greater than 1. The driving module provides driving signals to the scanned rows of light-emitting elements to drive the light-emitting elements for display. Thus, the successively scanned rows of light-emitting elements are not adjacent and are spaced apart by multiple rows, making the successively scanned rows of light-emitting elements as spatially dispersed as possible, which helps to reduce the flicker perception perceived by the human eye, thereby improving the display effect of the screen.

This application discloses a display panel and its driving method and display device. The display panel includes a gate driving circuit and sub-pixels. The gate driving circuit is connected to a trigger signal and a first clock signal. When both the trigger signal and the first clock signal are on, the light emission control signal output by the gate driving circuit controls the sub-pixels to emit light. The gate driving circuit includes multiple cascaded shift registers, which are used to drive n rows of sub-pixels, where n is an integer greater than or equal to 1. Within one frame, the duration difference between at least two cutoff levels of the trigger signal is t, where t≠0 and |t|≠2*n*H, where H is the scan duration corresponding to one row of sub-pixels. The embodiments of this application can improve the flicker problem of the display panel.

This application relates to a method, apparatus, and electronic device for processing vertex data in a high-precision map. The method includes: obtaining multiple vertex data arranged clockwise on a high-precision map; wherein the multiple vertex data correspond to multiple vertices that can form a concave polygon; segmenting the concave polygon to obtain multiple sub-polygons; triangulating each sub-polygon to obtain triangulated data corresponding to each sub-polygon; and concatenating the triangulated data corresponding to each sub-polygon to obtain the triangulated data corresponding to the concave polygon, which is used for rendering the high-precision map. The solution provided by this application can improve edge jaggedness and flickering of rendered graphics, thereby enhancing the display effect of high-precision maps.
