摘要:
An exemplary liquid crystal display (LCD) provides data lines, gate lines, and pixel units arranged as a matrix array. A method for driving the LCD includes a step of analyzing and determining polarities of one column of the pixel units as determining pixels, thereby defining a first polarity group and a second polarity group, and a step of sequentially applying corresponding data signals to a part of the whole pixel units that are arranged at same rows with the first polarity group in a part of a period of a frame. Corresponding data signals are sequentially applied to the other part of the whole pixel units that are arranged at same rows with the second polarity group in another part of a period of a frame.

An exemplary display device (10) includes a display screen (11), a protective screen (19), and a housing (13) accommodating the display screen. The housing includes a mechanism for fixing the protective screen immediately in front of the display screen. The mechanism is configured as grooves (133) in a front portion of the housing, or blocks (433) integrally formed with the housing, which conveniently provides fixing of the protective screen in front of the display screen.

An illumination circuit includes a series circuit including light sources connected in series between a high voltage node and a low voltage node, and break-protecting circuits. Each break-protecting circuit includes a control circuit and a bypass circuit. The bypass circuit is connected in parallel to at least one corresponding light source of the light sources. The control circuit is connected to the series circuit and the bypass circuit to detect a voltage change of the series circuit and control the bypass circuit to be in a conduct state or a blocked state according to the voltage change

An exemplary liquid crystal display (200) includes a liquid crystal panel (240) having pixel units (248), a scanning circuit (210) configured to activate the pixel units, and a power supply circuit (230) having a control unit (231) and a logic converter (232). The control unit generates a control signal when an external command is applied to the power supply circuit. The logic converter carries out a predetermined logic calculation between the control signal and the external command. The scanning circuit activates all the pixel units to discharge in response to a result of the logic calculation, such that an image displayed by the liquid crystal panel is removed.
