Benefits of technology

This patented technology prevents an increase or decrease in voltage supplied for displaying images on electronic devices due to changes over time caused by factors like temperature fluctuations during use. By controlling signals sent through certain circuits within the screen itself, it can achieve better image quality without increasing energy consumption compared with traditional methods that require constant voltages.

Problems solved by technology

This patented technology solves issues related to current methods for improving the quality of LMOS type organic eletrolled emission devices used in electronic equipment such as televisions or monitors. These improvements include reducing variations caused by changes made over time from temperature fluctuations affecting both the device's own characteristics and its ability to maintain consistency between different settings when compared against previous designs.

Embodiment Construction

[0021] An OLED display device and an aging method thereof according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0022] Existing OLED display panels have uneven brightness during the aging test and cannot meet the shipment requirements. The inventor has conducted in-depth research on this and found that the reason for the uneven brightness of the existing OLED display panel after aging is that the power supply voltage Vdd is affected by the impedance of the power supply line and there is a voltage drop (IRDrop), which makes different positions At the same time, the...

Abstract

The invention relates to an OLED display device and an aging method thereof. The OLED display device comprises a plurality of gate lines and a GIP circuit; the GIP circuit is provided with a plurality of input ends, wherein the plurality of input ends are used for receiving first control signals and second control signals respectively; the GIP circuit responds to the first control signals so as to drive a plurality of gate lines at the lower side of a display region; the GIP circuit responds to the second control signals so as to drive a plurality of gate lines at the upper side of the display region; and the plurality of input ends of the GIP circuit are respectively provided with a first switch. According to the OLED display device and the aging method thereof provided by the invention, the input ends of the GIP circuit of the OLED display device are provided with the switches, so that the input of the first control signals and the second control signals can be controlled, and therefore, block display can be realized, the drop of power source voltage can be decreased, and current which is adjacent to a power source and current which is far from the power source end will not be greatly different from each other, and as a result, uneven brightness can be alleviated, and the OLED display device can pass an aging test smoothly.
