first embodiment
[0052]The pixel unit 40 generally has the structure similar to the first embodiment, and has first and second pixel electrodes 411, 421 separated from each other. Referring to FIG. 5, each of the first and second pixel electrodes 411, 421 has a pattern scattered from a center in such a manner to form four domains. Each of the four domains of a respective one of the first and second pixel electrodes 411, 421 includes a plurality of parallel ribs extending in the predetermined inclined direction.
[0053]In the above embodiment, the first crystal capacitor Clc1 is formed by the first pixel electrode 411, the crystal layer 440 and the first common electrode 412, wherein the first common electrode 412 is formed on the upper substrate 400. The first storage capacitor Cst1 is formed by a first capacitor electrode 413, the first dielectric layer 460 and the second common electrode 414. The first storage capacitor Cst1 is coupled to the first crystal capacitor Clc1 in parallel while the second...
second embodiment
[0057]In the second embodiment, since the first and second storage capacitors Cst1 and Cst2 have different voltage levels, when the pixel unit 40 is under the operation, the first pixel electrode 411 and the second pixel electrode 421 may receive the voltage levels different from each other so as to result in two electric fields with differing strength. Thus, the orientation of the crystal molecules at the different domains differs from each other under the influence of the different electric fields.
[0058]Each of the first and second pixel electrodes 411, 421 has a pattern scattered from a center in such a manner to form four domains. The increased domains of the pattern in each of the first and second pixel electrodes 411, 421 from four to eight domains magnificently lower the color-shift in the changing view angle and the washout phenomenon, which, in turn, provides a better display ability.
[0059]In addition, by applying two different voltage levels Vcom2, Vcom3 respectively on th...
third embodiment
[0068]Therefore, in the third embodiment, the pixel unit 50 includes two subpixels SP, each of the subpixels is formed by a transistor, a crystal capacitor and a storage capacitor separated from one another.
[0069]It is noted that the pixel unit 50 of the PSA LCD panel has first and second pixel electrodes 511, 521 separated from each other. Referring to FIG. 7, each of the first and second pixel electrodes 511, 521 has a pattern scattered from a center in such a manner to form four domains. Each of the four domains of a respective one of the first and second pixel electrodes 511, 521 includes a plurality of parallel ribs extending in the predetermined inclined direction.
[0070]In each pixel unit, the first and second transistors 510, 520 are adapted to be switched on in response to the scan signal so as to permit the voltage signal to be transmitted from the data line 502 to the first and second pixel electrodes 511, 521, thereby driving the respective display domains. At this time, ...
