A reflective region where display is performed with reflection of incident light through a liquid crystal layer and a transmissive region where display is performed by transmission of light from a backlight are provided, and the reflective mode and the transmissive mode are switched. In the case of displaying a full-color image, a pixel portion includes at least a first region and a second region, a plurality of lights of different hues are sequentially supplied to the first region according to a first order, and a plurality of lights of different hues are also sequentially supplied to the second region according to a second order which is different from the first order. In the transmissive mode, the reflective region is made to display black, so that decrease in contrast due to reflection of external light at the reflective region is prevented.

To provide a circuit used for a shift register or the like. The basic configuration includes first to fourth transistors and four wirings. The power supply potential VDD is supplied to the first wiring and the power supply potential VSS is supplied to the second wiring. A binary digital signal is supplied to each of the third wiring and the fourth wiring. An H level of the digital signal is equal to the power supply potential VDD, and an L level of the digital signal is equal to the power supply potential VSS. There are four combinations of the potentials of the third wiring and the fourth wiring. Each of the first transistor to the fourth transistor can be turned off by any combination of the potentials. That is, since there is no transistor that is constantly on, deterioration of the characteristics of the transistors can be suppressed.

The present invention discloses a control circuit and a control method for liquid crystal pixels, wherein the control circuit for liquid crystal pixels comprises a preset charging module, a second-order programming module and a first-order programming module which are connected in sequence. The present invention firstly charges the preset charging module, and then programs the preset charging module by the second-order programming module to make a voltage reach a maintenance voltage required by display of an image by a liquid crystal screen; and finally, the first-order programming module stores electric quantity for display of a next frame image when the liquid crystal screen displays a current image under the maintenance voltage, i.e., at the same time that the current image is displayed, the electric quantity required for display of the next frame image is prepared in advance.

The present application provides a display panel, a fabrication method of a display panel, and a display device. The display panel includes a transparent display panel, and a dimming panel comprising a plurality of pixels for emitting light and is arranged on a side of the transparent display panel. The dimming panel includes an electrochromic layer, an electrolyte layer, and an ion storage layer stacked in sequence. The electrochromic layer and the ion storage layer includes a porous structure, and the dimming panel further includes a first transparent electrode layer disposed on a side of the electrochromic layer away from the electrolyte layer, and the first transparent electrode layer is patterned and disposed corresponding to each pixel.
