Problems solved by technology

[0004] Here, since the pixel electrodes PX1 and PX2 of the sub-pixel 10 are arranged up and down, it is suitable for the elongated sub-pixel layout, and the length of the common electrode COM and the gate metal trace is the length of the short side of the elongated shape; In the case of a square sub-pixel layout (corresponding to a better display effect), the length of the common electrode COM and the gate metal wiring increases, which greatly reduces the aperture ratio, and also leads to poor liquid crystal orientation.

Embodiment Construction

[0042] see figure 2A display 30 proposed by an embodiment of the present invention includes: a substrate 300 and gate lines (or scanning lines) such as GL(n)-GL(n+7) and data lines (or scanning lines) formed on the substrate 300 signal lines) such as DL(m) to DL(m+4). Gate lines GL(n)-GL(n+7) and data lines DL(m)-DL(m+4) are alternately arranged to define a plurality of sub-pixels 31; in this embodiment, every four sub-pixels 31 constitute a Pixel P, and each sub-pixel 31 in each pixel P may include a first color sub-pixel, a second color sub-pixel, a third color sub-pixel and a fourth color sub-pixel, such as a red (R) sub-pixel, a green ( G) sub-pixel, blue (B) sub-pixel and white (W) sub-pixel, but not limited thereto, the color displayed by each sub-pixel 31 can be selected from other colors of the color coordinates, for example, can be added or replaced by Yellow or other brighter colors. In other embodiments, at least four sub-pixels 31 can also form a pixel P.

Abstract

The invention provides a display, wherein each sub-pixel of the display is provided with a primary display area and a secondary display area respectively corresponding to a first pixel electrode and a second pixel electrode which are separated from each other; a gap formed between the first pixel electrode and the second pixel electrode is perpendicular to a gate line; the sub-pixel further comprises a coupling electrode, a first switching transistor, a second switching transistor and a sharing transistor; the coupling electrode is coupled with the capacitor of the first pixel electrode; both the first switching transistor and the second switching transistor are electrically connected to the same gate line and the same data wire and electrically connected to the first pixel electrode and the second pixel electrode respectively; and the sharing transistor is electrically connected to the gate line, the coupling electrode and the second pixel electrode. The invention further discloses a photoelectric device.

Description

technical field [0001] The invention relates to a display technology field, and in particular to a display and an optoelectronic device using the display. Background technique [0002] As technology continues to advance, displays that can save energy or increase brightness are becoming more and more important. Therefore, multi-primary color displays that can increase transmittance and reduce backlight energy consumption have been developed. Multi-primary color displays mainly increase the brightness of the display through the high transmittance of white sub-pixels; on the other hand, multi-primary color displays can also increase the brightness of the display by adding yellow or other brighter colors, and achieve power saving effects by increasing the brightness of the display. . In contrast, traditional displays, such as sub-pixels with only three colors of red (R), green (G), and blue (B), can provide limited brightness, so they can be used outdoors or when the external a...
