  • Patent number: 11852941
    Abstract: A cholesteric liquid crystal display device includes a solar cell, a first substrate, a shielding layer, a first electrode layer, a cholesteric liquid crystal layer, a second electrode layer and a second substrate stacked sequentially from bottom to top. The solar cell includes a metal wiring pattern layer. The shielding layer corresponds to the upper side of the metal wiring pattern layer, and is used to reduce the reflection of light from the metal circuit pattern layer. In this way, the cholesteric liquid crystal display device replaces the traditional black absorbing layer with the black material of the solar cell, which can not only absorb light, but also display the image with self-sustaining power. The cholesteric liquid crystal display device shields the arrangement of the metal wiring pattern layer through the shielding layer, which can ensure the image quality of the display panel.

  • Publication number: 20230368747
    Abstract: The present invention relates to a cholesteric liquid crystal display, a micro processing unit, and a method for hybrid driving. The cholesteric liquid crystal display comprises a display panel and a micro processing unit. First, a grayscale threshold value needs to be set in advance. The micro processing unit will change the grayscale value of the display unit exceeding the grayscale threshold value to the new grayscale value displayed by the bright state color, and display the image by the DDS driving mode. Then the micro processing unit drives the display image in the PWM drive mode, which can greatly improve the color level and contrast display effect of the image.

  • Patent number: 11746772
    Abstract: A miniature fluid transportation device is provided and includes a convergence component, a valve component, an outlet plate and a plurality of fluid transportation actuation components. The plurality of fluid transportation actuation components are disposed on the convergence component so as to transport the fluid to the convergence component. The convergence component guides the fluid transported by the fluid transportation actuation components to the outlet plate through the valve component. The outlet plate guides the fluid from different transportation actuation components back to the convergence component by a separation guiding block. The fluid is converged in a convergence central slot of the convergence component and is discharged out through a collection channel of the outlet plate. Consequently, the problem of interference owing to the convergence of the fluid transported by different fluid transportation actuation components can be avoided.
