More specifically, the backlight module 2100 includes a backplane 2110 and various light sources 2120 arranged on the backplane 2110 to provide various colors of light. In addition, the aforementioned light sources 2120 are, for example, red point light sources, blue light point light sources, and green light point light sources. In addition, the light source 2120 is, for example, a light emitting diode (light emitting diode, LED), an organic light emitting diode (organic light emitting diode, OLED) or other types of point light sources. In this embodiment, the backlight module 2100 is a direct type backlight module, and the light source 2120 is a point light source.

It is worth noting that neither the active element array substrate 2100 nor the opposite substrate 2200 has a color filter layer, so the color liquid crystal display 20 of this embodiment can achieve color display through the light source 2120 capable of emitting multiple colors of light.

In more detail, the active element array substrate 2210 includes a first transparent substrate 2212, an active element layer 2214 and a first alignment film 2216, wherein the active element layer 2214 is disposed on the first transparent substrate 2212, and the first alignment film 2216 is disposed on the active device layer 2214 .

The driving method includes: turn on the odd scan lines in turn, and sequentially input the first polarity signal and the second polarity signal to the pixel units controlled by the odd scan lines through the data lines at the odd positions, and input the signal through the data lines at the even positions. the first polarity signal to the pixel units controlled by the odd scan lines; and turn on the even-numbered scanning lines in turn, and sequentially input the second polarity signal and the first polarity signal to the pixel units controlled by the even-numbered scanning lines through the odd-numbered data lines and through the even-numbered data lines The second polarity signal is input to the pixel units controlled by the even scan lines.
