摘要： A liquid crystal display device having switchable viewing angles includes a display panel and a display control module. The display panel includes a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. The display control module is used for controlling the display panel to display images. The first substrate is provided with a first electrode. The second substrate is provided with a second electrode and a third electrode. The liquid crystal display device further includes a viewing angle control module. The display control module is further used to provide a synchronization signal to the viewing angle control module. According to the synchronization signal, when a next frame following a current frame on which a viewing angle switching signal is received starts to display, the viewing angle control module outputs a periodic alternating voltage for switching viewing angle to the first electrode.

摘要： An LCD with switchable viewing angle includes a first substrate, second substrate, and a liquid crystal layer. The first substrate is provided with a first electrode and a first alignment film. The second substrate is provided with a second electrode, a third electrode and a second alignment film. The liquid crystal molecules adjacent to the first alignment film are tilted at a first pretilt angle. The liquid crystal molecules adjacent to the second alignment film are tilted at a second pretilt angle. The first pretilt angle and the second pretilt angle have the same magnitude but are contrary in direction. When no bias voltage is applied to the first electrode, the LCD is displayed with a narrow viewing angle; and when a bias voltage is applied to the first electrode, the LCD is displayed with a wide viewing angle.

摘要： The present invention provides a source driving circuit and an LCD device. The source driving circuit includes output channels, and each output channel includes a first switch element, a second switch element, a first output end, and a second output end. The first switch element and the second switch element are respectively connected to the first output end and the second output end. When the first switch element is turned on, the output channel outputs a display signal, and when the second switch element is turned on, the output channel provides recycled charges which are generated when the display signal is changed from a positive voltage to a negative voltage. The source driving circuit can recycle charges to make the most of charges generated when the display signals change from positive voltages to negative voltages and reduce power consumption of the LCD device.

摘要： An LCD includes a first substrate, a second substrate, a liquid crystal layer between the first and second substrates, first and second alignment films respectively disposed on the first and second substrates. The first substrate comprises multiple scanning lines and multiple data lines intercrossed with the multiple scanning lines to define multiple pixel areas. Each pixel area comprises multiple electrically interconnected first electrodes and multiple electrically interconnected second electrodes. The first electrodes and the second electrodes are disposed on different layers and mutually intersected to define multiple sub-pixel areas. Each sub-pixel area further comprises two protrusion-shaped patterns facing each other on two adjacent first electrodes where the first electrodes and the second electrodes are not overlapped. An angle within a range of 5-20 degrees is defined between the vertex connection direction of the two protrusion-shaped patterns facing each other and the rubbing direction of the first and second alignment films.
