A memory device may include an access transistor, and a memory cell configured to store an item of information. The memory cell may include first and second electrodes configured to have different optoelectronic states corresponding respectively to two values of the item of information, and to switch between the different optoelectronic states based upon a control signal external to the memory cell, the different optoelectronic states being naturally stable in an absence of the control signal. The memory cell may also include a solid electrolyte between the first and second electrodes.

A display panel, a display device, and an electronic device are disclosed. The display panel includes a flexible substrate, a plurality of pixel islands, an electrochromic layer, and a plurality of force sensors. In response to a stretching length of a corresponding one of a plurality of flexible connection lines being greater than a preset value, each of the plurality of force sensors is configured to enable the electrochromic layer to be switched to a transparent state to allow light emitted from the display panel to pass therethrough. In response to the stretching length of the corresponding one of the plurality of flexible connection lines being less than the preset value, each of the plurality of force sensors is configured to enable the electrochromic layer to be switched to an opaque state to block the light emitted from the display panel.

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.
