In the case of a liquid crystal display device, usually a white halogen is mixed with red, green and blue pixels. The display principle is based on the content of the kneading surface to provide different voltages to drive the various halogens, so that the liquid crystal molecules in each element Rotating or tilting, because the light causes the light to penetrate the liquid crystal molecules "can produce different color levels to display the shirt image. However, when the user views or squints the liquid crystal display device, different color angles are perceived due to different viewing angles, and thus different color brightness is perceived, which is a problem of color shift. In general, in order to solve the problem of chromatic aberration, a liquid crystal display device generally divides each element in the display panel into a bright area and a dark area to collectively display a pixel data.

The area data is written to the first pixel capacitor 17; similarly, the second scan line 12 transmits a first scan signal to turn on the second thin film transistor 16, and the second data line 14 simultaneously passes through the second thin film transistor 16. The second region data is transferred to the second capacitor 18. The data of the first region is the data of the bright area, and the data of the second area is the data of the dark area. The data of the first area and the second area are combined to display the data. In this way, the display panel 1 can simultaneously display the bright area and the dark area in one unit of the pixel to improve the chromatic aberration of the display panel. ° However, since the display panel 利用 uses the first scan line u, the second trace line-data line 13 and the second data line 14 to display _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The data signal thus increases the load of the scan line driver circuit and the data line driver circuit' and the increased scan line reduces the aperture ratio ((4) ratio) of the display panel.

Please refer to FIG. 2. FIG. 2 is a schematic diagram of an active array substrate 2 according to the present invention. The active array substrate 2 includes a plurality of halogen elements 20 arranged in an array and row and row wires, and only a part of the elements and wires are shown in the drawing for convenience of explanation. On the pixel of the same row, a first sub-scanning line 21, a second sub-scanning line 22, and a voltage dividing element 23 are disposed, and the active array substrate 2 is driven by a scanning line driving circuit 5. In addition, the active array substrate 2 further includes a data line 26 for transmitting pixel data to the pixel 20. The voltage dividing component 23 has a first impedance 231 and a second impedance 232. The first impedance 231 is electrically connected to the second impedance 232 and the scan line driving circuit 5. The first impedance 231 and the second impedance 232 can be resistors, capacitors or inductors. In the present embodiment, a resistor is taken as an example. The first impedance 231 and the second impedance 232 divide a driving signal outputted by the scanning line driving circuit 5 into a first level signal and a second level signal, and are provided at the two ends of the first impedance 231 to The first sub-scanning line 21 and the second sub-scanning line 22. Wherein, the first quasi-signal signal and the second quasi-signal signal have the same timing to simultaneously output to the pixel 20; but the first quasi-signal and the second quasi-signal have different levels as the data line 26 The basis for writing data of different brightness or grayscale values. The pixel 20 is divided into a first area 24 and a second area 25, wherein the first area 24 is electrically connected to the first sub-scanning line 21 and the data line 26 for receiving the transmission from the first sub-scanning line 21. The first quasi-signal and the information provided by the data line 26. Similarly, the second area 25 is electrically connected to the second sub-scanning line 22 and the data line 26 to receive the second level signal and the data. The first region 24 includes a first switching element 241, a first liquid crystal capacitor 242, and a first storage capacitor 243.

Similarly, the second sub-scanning line ', receives the two-bit quasi-signal and transmits to the second region 25 to turn on the second switching element 2 51. At this time, the first switching element 241 and the first switching element 241 are filmed as the thin film of the first region 24 and the -=5=-pixel data. The transistor, according to the current-voltage characteristics of the thin film transistor, as long as the signals of the first switching element 251 are not the same, the pixel data written in the first region -= the second region 25 is different. The current-voltage characteristics of the first switching element 241 and the 201027212 second switching element 251 are as follows. ID=K x(fgs-vJ....................................3 where 'ID is thin film electricity The gate current of the crystal, VGS is the voltage difference between the gate and the source of the thin film transistor, Vth is the critical voltage of the thin film transistor, and K is a coefficient. From the above formula, the ID and VGS are positive. Correspondingly, the size of 1D can be controlled by changing Vgs. In addition, in this embodiment, it is assumed that the thin film electro-crystal system works in the saturation region, and if the thin-film transistor is operated in the linear region, the same result can be obtained. As described above, since the current magnitude of the ID controls the data line 26 to write the pixel data of the first region 24 and the second region 25. Therefore, it is only necessary to control the voltage of the gate terminal to change the gate and the source. The magnitude of the ID can be controlled by the voltage difference. In this embodiment, since the levels of the first level signal and the second level signal are different, the gates of the first switching element 241 and the second switching element 251 are input. The voltages are different, and thus the #-line 26 is different from the pixel data written to the first region 24 and the second region 25 by the reference time, thereby displaying different brightness or grayscale values. The difference between the dark areas of the bright areas can thus improve the chromatic aberration phenomenon.
