Problems solved by technology

[0003] However, due to the characteristics of organic materials, OLED devices are sensitive to changes in ambient temperature. If OLED devices work under high temperature conditions for a long time, non-recoverable long-term afterimages will be formed on the display screen, which will affect the display effect of the display device.

Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0043] As mentioned in the background art, OLED devices work under high temperature conditions for a long time, and unrecoverable long-term afterimages will be formed in the display screen, which affects the display effect of the display device. The inventors have found through research that the reasons for the above problems are as follows: OLED display devices have many excellent properties such as high brightness, clear chromaticity, and large viewing angle, and gradually occupy the market. Due to the character...

Abstract

The embodiment of the invention discloses a display device. The display device includes: a display panel; and a logic temperature control unit, wherein the logic temperature control unit is connectedto a signal transmission path of a signal driving the display panel, and the logic temperature control unit is used for reducing the size of the signal on the signal transmission path or reducing theduty ratio of the signal on the signal transmission path when the environment temperature is higher than or equal to the preset temperature. The technical scheme provided by the invention is adopted,when the environment temperature is too high, the size of a signal on a signal transmission path for driving the display panel is reduced through the logic temperature control unit; the logic temperature control unit is used for reducing the size of a power signal or reducing the duty ratio of a signal on a signal transmission path for driving the display panel, for example, reducing the duty ratio of a light-emitting control signal, so as to reduce the ambient temperature and avoid long-term ghosting caused by continuous high-temperature display of the display device.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display devices have many excellent properties such as high brightness, vivid chromaticity, and large viewing angle, and gradually occupy the market. [0003] However, due to the characteristics of organic materials, OLED devices are sensitive to changes in ambient temperature. If the OLED device is operated under high temperature conditions for a long time, non-recoverable long-term afterimages will be formed on the display screen, which will affect the display effect of the display device. Contents of the invention [0004] The invention provides a display device, which is used to protect the light-emitting device in the display device and avoid long-term afterimages in the display screen. [0005] In a first aspect, an embodiment of the present invention provide...
