Abstract

The invention discloses a display device and a driving compensation method thereof. The display device comprises a display panel; a driving circuit used for providing a driving signal to drive a pixel array in the display panel; an induction circuit sensitive to temperature and / or illumination intensity and comprises an input end; an output end; at least one sensing element connected between the input end and the output end, wherein the equivalent resistance of the at least one sensing element is changed along with the change of temperature and / or illumination intensity; a bias element connected with the output end, and the equivalent resistance of at least one sensing element and the equivalent resistance of the bias element divide the input voltage to obtain a detection voltage; and a control circuit connected with the induction circuit so as to receive the detection voltage and adjust the driving signal according to the detection voltage. The induction circuit is arranged inthe display panel, the temperature and / or the illumination intensity of the display panel are / is detected, the control circuit is arranged to adjust and obtain the driving signal corresponding to thetemperature or the illumination intensity, and the display quality of the display device is guaranteed.

Description

Technical field

[0001] The present invention relates to the field of display technology, in particular to a display device and a driving compensation method thereof. Background technique

[0002] With the development of display technology, narrow bezels of display panels are becoming more and more common.

[0003] Whether it is a liquid crystal display device or an organic light-emitting diode display device, the thin film transistor is an important component. When the temperature of the display panel decreases, the electron mobility of the thin film transistor becomes lower, resulting in poor charging characteristics of the thin film transistor. If the driving circuit in the display device still provides the same driving signal to the display panel, the display quality of the display panel will decrease. In addition, the liquid crystal or organic light-emitting diodes will also have poor compatibility with the same driving signal as temperature and light intensity change. Theref...
