The embodiment of the invention discloses a temperature detection device, method and display system. The temperature detection device includes: a temperature-sensitive clock circuit, a temperature-sensitive signal generation module, a sampling clock generation module and a sampling module. The temperature-sensitive clock circuit sends the temperature-sensitive clock that changes with the current temperature to the temperature-sensitive signal generation module and the sampling clock generation module; the temperature-sensitive signal generation module is used to generate a temperature-sensitive signal according to the temperature-sensitive clock, and the edge of the temperature-sensitive signal occurs On the first edge of the temperature-sensitive clock; the sampling clock generation module is used to generate a sampling clock according to the temperature-sensitive clock, and the edge of the sampling clock occurs on the second edge of the temperature-sensitive clock; the edge of the sampling clock triggers the sampling module to sample the temperature-sensitive signal , the sampling module obtains the temperature sampling value. The technical solution provided by the embodiments of the present invention can prevent the sampling module from sampling the edge of the temperature-sensitive signal, thereby avoiding sampling errors.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of temperature detection, in particular to a temperature detection device and a display system. Background technique [0002] The display system includes a display device and a temperature detection device, the temperature detection device is used to detect the current temperature, and the display device is used to display images. Among them, the gray-scale voltage required by the display device to produce the same brightness under different temperature conditions is different, so the voltage curve of the gray-scale voltage needs to be changed according to the current temperature, so that the display device can also be used under different temperature conditions. produce the same brightness. [0003] In the prior art, a clock is usually used to detect the temperature. Generally, a sampling clock that does not vary with temperature and a temperature-sensitive clock that varies with temp...
