2. Description of Related Art
With progress of display technology, pixel and driving circuit have been developed to satisfy demands for high resolution and low power consumption of mobile devices. Since how to improve display effects of display panels has gradually become a significant issue for the display panel manufactures, a sub-pixel rendering (SPR) technology has come into being for overcoming fabrication limitations and achieving good display quality.

However, the aforementioned arrangements of the sub-pixels and the data lines may cause additional power cost, particularly disadvantageous in a situation of displaying a full-screen image frame with a solid color, since the sub-pixels coupled to each of the data lines may respectively correspond to different colors along a column direction (e.g. the sub-pixels R, B, G and B are sequentially coupled to the data line DL1 along the column direction). For instance, when the display panel 130 is driven to display a full-screen image frame with a red color, a voltage transmitted on each of the data lines may be toggled between different voltage levels frequently for charging the sub-pixels R while discharging the sub-pixels G and B along the column direction, and thus a power consumption may be increased. Hence, how to design a display panel that is capable of overcoming the above problem is an important issue that needs to be solved.
