Abstract: An apparatus of approximating backlight spread is used in a display to estimate a backlight spread image corresponding to an image after backlight spreading of a plurality of backlight sources arranged in a matrix form. An equalizer receives backlight pulse width modulation signals of the backlight sources for performing an equalization operation and generating corresponding equalization signals. A backlight seed image constructor receives the equalization signals to establish a backlight seed image. A first calculation unit calculates positions corresponding to the backlight seed image based on a backlight spread image. A second calculation unit calculates coordinates of the backlight seed image corresponding to the positions. A distance calculator calculates distance differences between the positions and coordinates of the backlight seed image. A bilinear transformation unit performs a bilinear transformation on pixels of the backlight seed image and the distance differences so as to generate the backlight spread image.

Abstract: An apparatus compensates image in a backlight local dimming system for estimating pixels of the image after backlight spreading of a plurality of backlight sources in the backlight local dimming system. The apparatus includes a block dimming value decision unit, a quality/power-saving priority decision unit, a temporal filter, a backlight spread approximation unit, and an image compensation unit. The block dimming value decision unit calculates an average value, a maximum value and a initial value for each image block. The quality/power-saving priority decision unit generates a backlight control signal based on the average value, the initial value, and two thresholds. The temporal filter adaptively generates a backlight pulse width modulation signal based on the backlight control signal. The backlight spread approximation unit generates a backlight spread image based on the backlight pulse width modulation signal. The image compensation unit compensates the image based on the backlight spread image.

Abstract: A locking apparatus uses a handle pivotally connected to a base to control the movement of a slide block slidablely accommodated in a base. The slide block includes a locking tongue. The locking tongue protrudes out of the base or retracts back into the base according to the movement of the slide block. Thus, the locking apparatus can lock the hard disk when the locking tongue protrudes out of the base and unlock the hard disk when the locking tongue retracts back into the base.

Abstract: A locking mechanism includes a tray to receive a hard disk drive and a locking apparatus. The locking apparatus includes a base attached to a front wall of the tray, a handle pivotally connected to the base, and a locking member attached to the base. The base defines a receiving chamber and a mounting hole in communication with the receiving chamber. The locking member includes a sliding portion slidably received in the receiving chamber of the base to impel the handle to pivot relative to the base, and a locking tongue attached to the sliding portion. Movement of the locking tongue relative to the mounting hole causes the locking mechanism to toggle between a locked and unlocked position.

Interior of the plastic housing is defined with retaining grooves for inserting the contact terminal and the two signal terminals, and also embodies a main receptacle for plugging a butt sound source plug therein. An insulated protruding arm extends toward interior of the main receptacle of the plastic housing. The insulated protruding arm of the plastic housing and the flexible terminal are mutually close, and moreover, the flexible terminal is adjacent to the contact terminal. The two signal terminals extend into the interior of the main receptacle of the plastic housing. Upon the sound source plug pushing on the insulated protruding arm, the flexible terminal comes in contact with the contact terminal, thereby enabling the flexible terminal and the contact terminal to transmit same signals.
