Problems solved by technology

The increase in temperature will shorten the life of the organic electroluminescent device, especially the pixels close to the source drive structure (Source IC), which receive a higher drive current than the pixels far away from the source drive structure. High, more heat generation, resulting in shorter lifetime of organic electroluminescent devices close to the source drive structure

Abstract

The present invention provides a display device, including a display substrate, the display substrate includes a display area and a driving area, a plurality of data lines are arranged in the display area, a source driving structure is arranged in the driving area, the display The substrate is cylindrical, the data lines are arranged around the axis of the display substrate, each data line has a first end and a second end, and the first ends of different data lines are located on the same side of the display area; the source The pole driving structure includes a plurality of output pins on opposite sides thereof, and each output pin is connected to a data line; wherein, the output pin on one side of the source driving structure is connected to the first end of the corresponding data line The output pin on the other side of the source driving structure is connected to the second end of the corresponding data line. The invention is beneficial to dissipate the heat on the display substrate, thereby improving the service life of the organic electroluminescence device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] The organic electroluminescent (OLED, Organic Light-Emitting Diode) panel has characteristics such as active light emission and easy bending. The organic electroluminescent device emits light under current driving. When the brightness of the organic electroluminescent display panel is higher, the required driving current is larger, and the display panel generates more heat. The increase in temperature will shorten the life of the organic electroluminescent device, especially the pixels close to the source drive structure (Source IC), which receive a higher drive current than the pixels far away from the source drive structure. Higher, more severe heat generation, resulting in shorter lifetime of organic electroluminescent devices close to the source drive structure. Contents of the invention [0003] The present inventi...
