In the above two embodiments, the display panel 100 includes S/D units 10 distributed on two opposite sides of the display panel 100. The S/D units 10 are longitudinally or transversely alternately connected to data lines 30 of the display panel 100. The drive method includes the following steps.
S10: Control an input signal of a system end to be output as a data signal and a control signal.
S20: Control the S/D units to charge the respectively connected data lines of the display panel.
S30: Control a gate drive signal to be input to display the input signal.
Under a normal circumstance, a display panel includes a timer control register (TCON), an S/D, a G/D, a data line (or a signal line) and a scan line. The TCON is configured to process an input image signal into a data signal and a control signal for transmission to the S/D and the G/D respectively. The S/D is responsible for providing data required to be displayed by the display panel, connected to a source of a thin film transistor and responsible for charging a liquid crystal capacitor. The G/D is responsible for level control of a gate of the thin film transistor of the display panel. When an image is displayed, the S/D provides a charging voltage for the data line of the display panel and the G/D outputs a voltage through the scan line to control the thin film transistor of the display panel to be switched on and off for display of the image signal.
According to the display panel of the present disclosure, to lighten a load of the S/D, an S/D unit 10 is arranged on each of the two opposite sides of the display panel 100. The S/D units 10 are longitudinally or transversely alternately connected to the data lines 30 of the display panel 100 and charge the respectively connected data lines 30 of the display panel 100. The phenomenon of non-uniform cutting formed at a middle position of the display panel due to the fact that the S/D units are adopted for charging from the two sides to the middle in an existing display panel is avoided.
The display panel 100 of the present disclosure includes the S/D units 10 distributed on the two opposite sides of the display panel 100, and the S/D units 10 are alternately connected to the data lines 30 of the display panel 100 and charge the data lines 30 of the display panel 100. In such a manner, the S/D units 10 on the two sides of the display panel 100 provide charging voltages for the respectively connected data lines 30 of the display panel 100 when the display panel 100 is driven for display. Therefore, non-uniform cutting caused by inconsistent attenuation of gamma voltages and voltages on the data lines is avoided and a display effect of the display panel is improved.
Furthermore, referring to
According to the display drive method of the present disclosure, the two S/D units 10 are controlled according to an architecture composition of the display panel 100 and according to the output data signal to simultaneously input the charging voltages to the respectively connected data lines 30 of the display panel 100 to charge the liquid crystals in the display panel 100, and then the gate drive signal is controlled to be input according to the output control signal to display the input signal. The condition that a cutting line is formed due to non-uniform display at the middle position of the display panel under influence of non-uniform impedance of the display panel when the S/D units charge the middle position of the display panel through the data lines is avoided, and the display effect of the display panel 100 is improved.

For example, each group may include 1, 2 or 3 data lines. The multiple groups of data lines 30 which are alternately arranged are divided into the odd groups and the even groups according to a sequence of the groups. To further improve the display effect of the display panel 100, each of the odd groups and the even groups includes a same number of data lines 30, so that the data lines 30 in any region of the display panel 100 can maximally obtain the input voltages of the S/D units 10 on the two sides for complete mixing, and the probability of forming non-uniform cutting at the middle position is effectively reduced. The S/D units 10 distributed on the two sides of the display panel 100 include the first S/D unit 11 and the second S/D unit 13, the first S/D unit 11 is connected to the odd groups of the multiple groups of data lines 30 and the second S/D unit 13 is connected to the even groups of the multiple groups of data lines 30.
