Based on the hardware architecture of the display, an embodiment of the driving method of the display of the present invention is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a driving method of a display according to the present invention, the driving method of the display includes the steps of:
step S10, when receiving the control signal sent from the timing controller, the voltage converter turns on the target voltage sent to the gamma corrector and the data line, and turns on the on-voltage or off-voltage sent to the gate line;
specifically, the display comprises a time sequence controller and a voltage converter, wherein the time sequence controller is in communication connection with the voltage converter, the voltage converter is in communication connection with the source electrode driver and the gamma corrector, and the time sequence controller is in communication connection with the grid electrode driver. The voltage converter is a DC/DC converter, which is a switching power supply chip, and the DC/DC converter performs a high-frequency switching operation by a controllable switch using the energy storage characteristics of a capacitor and an inductor. The control signal may be an EN signal, which is a signal for turning on the operation of the voltage converter. The target voltage is the VAA signal, the turn-on voltage is the VGH voltage, generally 20v-35v, and the turn-off voltage is the VGL voltage, generally-5 v.
When the display is detected to be started, the voltage converter controls the gamma corrector and the target voltage of the data line and the on-voltage or the off-voltage of the gate line to be in an off state. As shown in fig. 3, the target voltage is used to provide power to the gamma corrector C and the source driver F, the on-voltage and the off-voltage are used to provide power to the gate driver E, the on-voltage is the on-voltage of the thin film transistor of the display panel D, and the off-voltage is the off-voltage of the metal oxide semiconductor field effect transistor of the thin film transistor switch of the display panel D. When the voltage converter A receives the control signal sent by the timing controller B, the voltage converter A starts a target voltage of the gamma corrector C and the data line which are in communication connection with the voltage converter A, and starts a turn-on voltage or a turn-off voltage sent to the gate line, wherein the timing controller B sends the control signal to the voltage converter A within a preset time length before the start signal of the clock signal.
Step S20, the voltage converter receives the clock signal sent by the timing controller;
specifically, the voltage converter receives a clock signal sent by the timing controller, the clock signal is used for determining when the state of the voltage converter is updated, and the clock signal has a fixed clock period and a fixed clock frequency, wherein the clock frequency is the reciprocal of the clock period.
In step S30, after the clock signal is ended, the voltage converter turns off the target voltage between the gamma corrector and the data line, and turns off the on-voltage or off-voltage of the gate line.
Specifically, after the clock signal is over, the display is in the gap time between two image frames. The voltage converter turns off a target voltage of the gamma corrector and the data line and an on-voltage or an off-voltage of the gate line.
In the technical solution of this embodiment, when receiving the control signal sent by the timing controller, the target voltages of the gamma corrector and the data line and the on-voltage or off-voltage of the gate line are turned on, the clock signal sent by the timing controller is received, and after the clock signal is ended, the target voltages of the gamma corrector and the data line and the on-voltage or off-voltage of the gate line are turned off. By controlling the voltage of the gamma corrector, the data lines and the grid lines to be switched on and off, the power consumption of a screen is reduced and the service life of a driver is prolonged under the condition of ensuring the normal display of images.
Referring to fig. 4, fig. 4 is a second embodiment of a driving method of a display according to the present invention, the driving method of the display includes:
step S40, the timing controller generates a clock signal corresponding to an image frame to be displayed;
step S50, the time schedule controller obtains the active time and blank time of the image frame to be displayed;
step S60, when the image frame to be displayed is in active time, the timing controller sends the clock signal to a voltage converter;
in step S70, when the image frame to be displayed is in a blank time, the timing controller stops sending the clock signal to the voltage converter.
Specifically, before the timing controller generates the clock signal corresponding to the image frame to be displayed, the method further includes: the time schedule controller determines an initial signal of a clock signal according to a preset refresh rate; and in a preset time length before the initial signal, the time schedule controller sends a control signal to the voltage converter so that the voltage converter starts the target voltage of the gamma corrector and the data line and the turn-on voltage or the turn-off voltage of the grid line.
The time schedule controller acquires active time and blank time of an image frame to be displayed, and determines the last clock signal corresponding to the image frame to be displayed according to a preset period of the clock signal; determining a time interval from a starting signal to a last clock signal as an active time; the time interval between the last clock signal and the next start signal is determined as a blank time. Illustratively, as shown in fig. 5, the STV denotes a start signal, and the STV signal is a signal for controlling the source driver to scan. The timing controller may determine a last clock signal CLK corresponding to the image frame to be displayed according to a preset period of the clock signal CLK, and determine a time interval from the start signal STV to the last clock signal CLK of the image frame to be displayed as an active time, where the active time is a time for displaying the image frame to be displayed. In the active time, the target voltage VAA and the on voltage VGH, or the target voltage VAA and the off voltage VGL are on. The time interval of the last clock signal CLK and the start signal STV of the next image frame to be displayed is determined as a blank time, which is a loading time between image frames to be displayed. In the active time, the target voltage VAA and the on voltage VGH, or the target voltage VAA and the off voltage VGL are off. By determining the blank time and the active time control voltage, the power consumption of the screen is reduced on the premise of not influencing image display.
The time sequence controller generates a clock signal corresponding to the image frame to be displayed, acquires the active time and the blank time of the image frame to be displayed, and sends the clock signal to the voltage converter when the image frame to be displayed is in the active time. When the image frame to be displayed is in the blank time, the time schedule controller stops sending the clock signal to the voltage converter, and the voltage converter turns off the target voltage of the gamma corrector and the data line and the on-voltage or off-voltage of the gate line after not receiving the clock signal.
In the technical scheme of the embodiment, the time schedule controller generates a clock signal corresponding to an image frame to be displayed; when an image frame to be displayed is in an active time, sending a clock signal to a voltage converter; and when the image frame to be displayed is in the blank time, stopping sending the clock signal to the voltage converter. The time controller sends clock signals to control the voltage converter to turn off the voltage, and the loading time between image frames reduces the power consumption, thereby reducing the screen power consumption.
