Abstract: A liquid crystal backlight device and a method for controlling the same are applied to a liquid crystal display apparatus, in which a backlight module is disposed behind a liquid crystal panel to illuminate the panel. The backlight device produces stable illumination to solve the hold type problem due to the hold-type effect of liquid crystal occurred in the prior art. The control method is used to acquire a stable display time from the liquid crystal characteristics and then process the scan signal to match the display data. Controls of the backlight activation signal, including on/off, time delay, and duty cycle adjustment, are then performed to generate a pulse-width modulated signal and a brightness modulated signal so as to produce stable backlight illumination effect. A better display effect can therefore be accomplished.

Abstract: A connector cover assembling system includes an arrangement apparatus, which aligns covers and includes a transporting channel for transporting the covers to a frame that supports the covers and associated connector bodies. A cover driving member transports the covers one by one from the frame to a separating mechanism, which further transports the cover to a location above a clamping mechanism for being clamped by the clamping mechanism.

When the operating portion is pushed inward, the bias portion displaces inward correspondingly and disengages from the stop grooves.

Abstract: An LCD (Liquid Crystal Display) Device of improvement of flicker upon switching frame rate and method for the same are proposed. The LCD device includes a pixel matrix, a timing controller and a gate driver. The timing controller outputs a first Gate-On-Enable signal to the gate driver, when the LCD device displays frame according to a first frame rate. When the first frame rate is switched to a second frame rate, the timing controller outputs a second Gate-On-Enable signal to the gate driver to cause a charge time of the pixel matrix to be unchanged. It is appreciated that a pulse width of the second Gate-On-Enable signal is equal to a summation of a pulse width of the first Gate-On-Enable signal and an adjusted pulse width.
