Embodiment 1

[0066] In order to solve the afterimage caused by too few Vgs, Embodiment 1 of the present invention provides a display control method. The flow chart of the method is shown in Figure 5 shown, including:

[0067] S101, setting the current driving voltage of the thin film transistor TFT as the initial driving voltage;

[0068] S102, detecting the continuous display time of the current frame image;

[0069] S103, determining a target driving voltage corresponding to the continuous display time;

[0070] S104. Adjust the current driving voltage according to the target driving voltage.

[0071] Applying the embodiment of the present invention, by detecting the change of the continuous display time of the current frame image, determining the corresponding target driving voltage, and further adjusting the current driving voltage of the TFT according to the target driving voltage, the number of current driving voltages can be increased, The increase in the number of current driv...

Embodiment 2

[0094] Based on the same inventive concept, Embodiment 2 of the present invention provides a display control method. The flow chart of the method is shown in Figure 6 As shown, on the basis of S101-S104 in Embodiment 1 of the present invention, the method further includes:

[0095] S105, when it is determined that the continuous display time is less than or equal to the first preset time, and it is detected to switch to the next frame image for display, determine the image difference value between the next frame image and the current frame image;

[0096] S106, judging whether the image difference value is greater than the preset image difference threshold; if so, the next frame image is regarded as a different image from the above-mentioned current frame image, and step S101 is performed; if not, the difference can be ignored, and the next frame is regarded The image is the same image as the above-mentioned current frame image, and step S107 is executed.

[0097] Step S107...

Embodiment 3

[0116] Corresponding to Embodiment 1, Embodiment 3 of the present invention provides a display device. The schematic diagram of the display device is shown in Figure 8 As shown, it includes a voltage setting module 401 , a time detection module 402 , a voltage determination module 403 and a voltage regulation module 404 connected in sequence as described in the third embodiment.

[0117] The voltage setting module 401 is used to set the current driving voltage of the TFT as the initial driving voltage; and is specifically used to: set the initial control signal of the voltage adjustment module 404, and output a corresponding Vgl under the control of the initial control signal, as the initial driving voltage.

[0118] The voltage setting module 401 uses the initial driving voltage as the main voltage of the driving voltage to fix the main voltage of the driving voltage, which can avoid switching the driving voltage at multiple voltage values, so that when the LCD does not dis...

Abstract

Embodiments of the invention provide a display control method and a display apparatus. The method includes: setting a current driving voltage of a thin film transistor TFT as an initial driving voltage; detecting a continuous display time of a current frame image; determining a target driving voltage corresponding to the continuous display time; and adjusting the current driving voltage accordingto the target driving voltage. According to the method, the change of the continuous display time of the current frame image is detected, the corresponding target driving voltage is determined, the current driving voltage of the TFT is further adjusted according to the target driving voltage, the number of the current driving voltages can be increased, and the drift of the TFT and the afterimage caused thereby can be reduced.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular, the present invention relates to a display control method and a display device. Background technique [0002] In recent years, liquid crystal displays have become popular in the market due to their advantages of low operating voltage, low power consumption, low radiation, low space occupation rate, and thin, light and beautiful appearance. With the continuous improvement of people's awareness level and display requirements, higher and higher requirements are put forward for the picture quality of the display. However, there are still the following problems in the picture quality of liquid crystal displays currently on the market: [0003] When TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) displays the same picture for a long time, because the liquid crystal is driven by a long-term DC bias voltage, the liqu...
