The normally understood meaning of technical staff is identical.Used term is intended merely to description tool in the description of the invention herein
The purpose of the embodiment of body is not to be to limit the present invention.
Referring to Fig. 1, one embodiment of the application provides a kind of display panel 100, including substrate 110, the substrate
110 include viewing area 111 and non-display area 112.Wherein, viewing area 111 includes the pixel unit 101 of array arrangement.It is non-display
Area 112 is set to 111 periphery of viewing area, and for driving circuit, conducting wire etc. to be arranged, drive signal is provided for pixel unit.Display
Panel 100 further includes driving unit (not shown), working power 113 and compensation power supply 114.Wherein 113 He of working power
Compensation power supply 114 is set to non-display area 112, and is located at the both ends of viewing area 111.Driving unit connects working power
113 and compensation power supply 114, for drive working power 113 and compensation power supply 114 be pixel unit 101 power supply.
Embodiments herein equipped with working power and compensates power supply simultaneously in the non-display area of above-mentioned display panel.It is described
Working power is located at one end of viewing area, and connects the pixel unit in viewing area and provide working power electricity for pixel unit
Pressure.Compensation power supply is located at the other end of viewing area, and connects the pixel unit in viewing area, is pixel list from the viewing area other side
Member provides compensation supply voltage, compensates pixel unit voltage loss caused by signal line resistance far from working power, makes to show
Show that the supply voltage of the pixel unit in each region in area is identical, pixel current is identical, and then display brightness is also identical, has prevented display
The phenomenon that brightness irregularities.
As one of embodiment, non-display area 112 further includes working power 113 and compensation power supply 114.Working power
