A composite display device includes a composite display, a brightness acquisition module, an image management module and a panel controlling module. The composite display includes a first display panel and a second display panel. The brightness acquisition module is connected to the composite display and acquires an ambient brightness around the composite display. The image management module is connected to the brightness acquisition module and generates a first image setting signal and a second image setting signal according to the ambient brightness. The panel controlling module is connected to the image management module and the composite display, and respectively controls the first display panel and the second display panel to display a first and second images based on the first and second image setting signals to form a composite image.

Composite display device and controlling method thereof

A self-powered display device is proposed, and includes a light-transmitting panel and a photoelectric converting module. The light-transmitting panel has a display region for allowing light to penetrate. The photoelectric converting module is electrically connected to the light-transmitting panel. The photoelectric converting module has a power generation region for absorbing the light penetrating the display region, and the photoelectric converting module converts the light into an electrical energy through the power generation region to provide the electrical energy to the light-transmitting panel. The light-transmitting panel is spaced apart from the photoelectric converting module, and a projected area of the display region on the power generation region is larger than an area of the power generation region.

Self-powered display device

The present disclosure provides a method for driving a cholesteric liquid crystal display device. The method includes the following steps: utilizing a driving circuit section to sequentially activate each scanning electrode within a display panel; utilizing the driving circuit section to apply first alternating-current (AC) voltage pulses to pixel circuits on an activated scanning electrode during a first stage within a pulse-width modulation (PWM) scanning procedure of an activated scanning electrode; and utilizing the driving circuit section to apply second AC voltage pulses to the pixel circuits on the activated scanning electrode during a second stage of the PWM scanning procedure. A first voltage amplitude and a first period of the first AC voltage pulses are different from a second voltage amplitude and a second period of the second AC voltage pulses, respectively.
