Problems solved by technology

[0002] The known liquid crystal display device will be affected by temperature changes, which will cause the gate drive circuit disposed on the substrate of the liquid crystal display device to have an excessive leakage current or a low driving current, which will lead to abnormal display screens. Therefore, the liquid crystal display device needs The temperature detection element adjusts the operating voltage of the gate drive circuit by grasping the current temperature at any time, so that the liquid crystal display device can display images normally without being affected by temperature changes. Therefore, how to accurately detect the current temperature of the substrate by the temperature detection element is a subject.

Abstract

Provided is a temperature sensing circuit for a display, the display and an operation method thereof. The sensing circuit comprises a temperature sensing module, a reading module and a resetting module. The temperature sensing module can provide a sensor voltage potential according to a sensed temperature. The reading module is used for receiving the above sensor voltage potential, and determines whether to output the sensor voltage potential according to a first control signals. The resetting module is used for receiving a second control signal and determines whether resets the sensor voltage potential to be a low-voltage potential according to the second control signal.

Description

technical field [0001] The present invention relates to a temperature sensing circuit, in particular to a temperature sensing circuit applied to a display and an operation method thereof. Background technique [0002] The known liquid crystal display device will be affected by temperature changes, which will cause the gate drive circuit disposed on the substrate of the liquid crystal display device to have an excessive leakage current or a low driving current, which will lead to abnormal display screens. Therefore, the liquid crystal display device needs The temperature detection element adjusts the operating voltage of the gate drive circuit by grasping the current temperature at any time, so that the liquid crystal display device can display images normally without being affected by temperature changes. Therefore, how the temperature detection element can accurately detect the current temperature of the substrate is a subject. Contents of the invention [0003] In order ...
