AI Technical Summary

Technical Problem

The uneven display effect in different areas of the monitor is due to the different connection node positions of the vertical and horizontal SWEEP traces, resulting in different signal waveforms.

Method used

A sweep signal line is provided in the display device, including a first sweep signal line extending along a first direction and a first connecting line extending along a second direction. By adjusting the number and position of the connecting line and the number of electrically connected sweep signal lines, the number of electrical connection nodes is increased and the load difference is reduced.

Benefits of technology

This improves the display effect of the display device, reduces the display difference between the light-emitting elements on the side away from the signal line node and the side near the node, and achieves a more uniform display.

Abstract

The application discloses a display device, and relates to the technical field of display, which comprises a display panel, the display panel comprises a plurality of light emitting elements and a plurality of pixel circuits; the pixel circuit comprises a pulse width modulation module, the pulse width modulation module is used for controlling the light emitting time length of the light emitting element; a scanning signal line, the scanning signal line provides a scanning signal for the pulse width modulation module; the scanning signal line comprises a first scanning signal line extending along a first direction, at least two first scanning signal lines are connected through a first connecting line, the first connecting line extends along a second direction, and the second direction intersects with the first direction. By adjusting the setting number and setting position of the first connecting line and the number of the electrically connected first scanning signal lines, the number of nodes where the first scanning signal line and the first connecting line are electrically connected in the display area is increased, the difference in transverse load far from the first scanning signal line is reduced, the display difference between the light emitting elements at different positions is weakened, and the display effect of the display device is improved.
