[0040] Please refer to figure 2 , which shows an example of the schematic diagram of the liquid crystal display according to the first embodiment of the present invention. The liquid crystal display 200 includes scanning lines GL(1) to GL(N), GR(1) to GR(N), data lines D(1) to D(M+1), a liquid crystal display panel 220, a gate driver 240 and a source driver 260 . N and M are respectively a positive integer.

[0041] The liquid crystal display panel 220 includes several pixel units, such as pixel units P1 to P4. The pixel units P1 and P3 are located in odd pixel columns, and the pixel units P2 and P4 are located in even pixel columns. The pixel unit P1 includes a liquid crystal capacitor Clc1, switches T1 and T1'. The pixel unit P2 includes a liquid crystal capacitor Clc2, switches T2 and T2'. The pixel unit P3 includes a liquid crystal capacitor Clc3, switches T3 and T3'. The pixel unit P4 includes a liquid crystal capacitor Clc4, switches T4 and T4'.

[0065] Please refer to Figure 4 , which shows an example of the schematic diagram of the liquid crystal display 400 according to the second embodiment of the present invention. Similarly, in the second embodiment, the pixel units P1' to P4' of the liquid crystal display panel 420 of the liquid crystal display 400 are taken as an example to illustrate the operation of each pixel unit in the liquid crystal display panel 420. Different from the first embodiment, the switches T2 and T4 in the pixel units P2' and P4' switch the pixel voltages on the data lines D(2) and D(3) to Stored in liquid crystal capacitors Clc2 and Clc4. The switches T2' and T4' respectively enable the pixel voltages of the data lines D(1) and D(2) to be stored in the liquid crystal capacitors Clc2 and Clc4 when the scan line GR(2) is enabled.

[0066] The driving method of the liquid crystal display 400 of this embodiment will be described below with a timing diagram. Please also refer to Figure 5 , wh...

Abstract

The invention discloses a liquid crystal display panel, which comprises a first scanning line, a second scanning line, a first data wire, a second data wire and a first pixel unit, wherein the first scanning line is enabled in a scanning period in a first image period and disabled in a second image period; the second scanning line is enabled in a scanning period in the second image period and disabled in the first image period; the first data wire is used for transmitting a first data signal; the second data wire is used for transmitting a second data signal; the first pixel unit comprises a first liquid crystal capacitor, a first switch and a second switch; the first switch is controlled by the first scanning line, and when the first scanning line is enabled, the first switch transmits the first data signal to the first liquid crystal capacitor; and the second switch is controlled by the second scanning line, and when the second scanning line is enabled, the second switch transmits the second data signal to the first liquid crystal capacitor.

Description

technical field [0001] The present invention relates to a display panel, and in particular to a liquid crystal display panel and a driving method thereof. Background technique [0002] In a liquid crystal display, the polarity of the pixel voltage is switched every once in a while to avoid damage to the physical properties of the liquid crystal molecules in the pixel. Common driving methods thereof are, for example, dot inversion and column inversion. As far as the picture characteristics of the display are compared, the picture quality of the dot inversion liquid crystal display panel produced by the dot inversion driving method is relatively good. However, in the conventional liquid crystal display panel, because of the dot inversion driving method, the frequency of the polarity inversion of the signal voltage is relatively frequent, resulting in a problem of high power consumption. [0003] In order to reduce the power consumption required by the dot inversion liquid cr...
