AI Technical Summary

Technical Problem

Under low temperature conditions, the response time of the liquid crystal layer in the liquid crystal display device is prolonged, which causes the image signal to be not fully activated before the backlight is turned on, resulting in a blurry screen.

Method used

By increasing the frame rate of the liquid crystal display device or adjusting the control strategy of the backlight and scan lines under low temperature conditions, it is ensured that the liquid crystal layer is fully activated and the front backlight is turned on, including controlling the number of scan lines and the scan time during the non-bright period within the vertical synchronization signal cycle.

Benefits of technology

It effectively prevents image blurring at low temperatures while maintaining image quality and ensuring a clear display.

Abstract

To provide a display device capable of preventing occurrence of blur of an image caused by low temperature while maintaining image quality, and to provide a control method of the display device.SOLUTION: The display device 100 includes a control circuit 4 and a temperature sensor 6. The control circuit 4 causes the gate drive circuit 2 to transmit the gate signal to the plurality of gate lines 11 in a non-lighting period that is a period other than the lighting period in one cycle of the vertical synchronization signal. When the detected temperature Ad is lower than the first temperature Ath1, the control circuit 4 sets the set number, which is the number of gate lines 11 to which the gate signal is supplied from the gate driving circuit 2 in one cycle of the horizontal synchronization signal, to a first number larger than one.SELECTED DRAWING: Figure 1
