Abstract: A liquid crystal display device and a viewing angle switching method are provided. The liquid crystal display device includes a display panel, a backlight source, and a light adjustment liquid crystal film disposed between the display panel and the backlight source. The light adjustment liquid crystal film includes an upper substrate, a lower substrate disposed opposite to the upper substrate, and a liquid crystal layer located between the upper substrate and the lower substrate. The upper substrate is provided with an upper electrode on a side thereof facing the lower substrate. The lower substrate is provided with a lower electrode on a side thereof facing the upper substrate. The light adjustment liquid crystal film is configured to change a backlight exit angle of the light emitted by the backlight after passing through the display panel by applying a voltage between the upper electrode and the lower electrode.

Abstract: A touch display device includes a first substrate, a second substrate opposite to the first substrate, a display medium sandwiched between the two substrates, and a touch-sensitive layer including sensitive electrode lines. The first substrate includes a first surface facing the display medium layer and a second surface far away from the display medium layer and opposite to the first surface. The touch-sensitive layer is disposed on the second surface of the first substrate, and first pins are disposed on a side area of the first substrate corresponding to a side of the touch display device to connect the sensitive electrode lines. Second pins are disposed on a side area of the second substrate corresponding to the same side of the touch display device, and connected to the first pins via a first printed circuit board (PCB). The first PCB is a flexible PCB.

Abstract: Reserve a plurality of blocks in a flash. Write a plurality of hot data into the plurality of blocks in a cyclic and sequential manner. After completing a cycle of writing data and hot data is to be written into the plurality of blocks, send a logic block address corresponding to hot data of a page to a cold/hot data identifying engine if the hot data of the page of a decay block are not updated. And the cold/hot data identifying engine decays a count of a counter corresponding to the logic block address according to the logic block address.

Abstract: A “water supply cap” is a device that is assembled with a bottle that loads drinking water to dispense the drinking water after the assembled unit is placed upside down; it comprises of a stand and a support collar that is installed on top of the opening of a drinking water bottle. Combination of the stand and the support collar provides a canal to discharge the drinking water and an air channel to balance the barometric pressure inside and outside of the drinking water bottle so as to ensure smoother water discharge.

Abstract: The present invention is a sphere container including a main body and several interchangeable caps, wherein the main body, being an upper semi-sphere joining with a lower semi-sphere of a larger diameter, having a top cut away to leave a circular opening for connecting with a short hollow cylinder as a capped section and a bottom cut away to form a base for standing on a surface, the cap having a capping section corresponding to the capped section, threads formed on the outer perimeter of the capped section and the corresponding capping section, and patterns formed on the outer surface of the sphere container, thereby enabling the sphere container being in vivid sundry appearances like a football, a basketball, or a baseball and having multiple applications when in different caps.

Abstract: A liquid crystal display device having a sealing material close to display area while maintaining a uniform liquid crystal cell gap is disclosed. The liquid crystal display comprises two transparent electrode substrates having a trench near the display area to stop the sealing material overflowing to display pixels. Thus, the effective display area of a liquid crystal display device is increased by dispensing a sealing material to a trench area at a predetermined position surrounding the display area. A spacer used in the sealing material is larger in size than that used in the display area to compensate the depth of the trench. After the liquid crystal is injected into the space surrounded by the substrates and a sealing material, a uniform liquid crystal cell gap over the entire display area is obtained.
