Abstract: An image data compression method is disclosed. Firstly, check a variance between a first image data and a second image data for comparing the variance with a threshold value. When the variance is smaller than a threshold value, compare the first image data with the second image data to generate a motion vector and compress the motion vector. Then calculate the first image data and the second image data according to the motion vector so as to get an offset value of the motion vector. Next, encode the offset value of the motion vector, compress the offset value of the motion vector, and encode as well as compress the first image data. Thus the compression ratio is improved and image distortion is avoided.

Abstract: A backlight module includes a frame (55) including a spring element (556), a light guide plate (56) disposed in the frame including an incident surface (561), and a radiation element (59) being pressed onto the incident surface by the spring element. The spring element presses the radiation elements against the light guide plate, and thereby decreases the distance and angle between the radiation elements and the light guide plate. This improves the brightness and uniformity of the emitting luminance of the backlight module.

Abstract: A keyboard module includes a plurality of key units, each of which is provided below a cap member thereof with an array of light-emitting elements. Under the control of a keyboard control circuit in the keyboard module, the light-emitting elements below each cap member are selectively driven to emit light, which is projected toward the cap member to show a specific character on a top surface of the cap member. A key switch is located below the cap member and is actuated to generate and send a key signal to the keyboard control circuit when the cap member is depressed.

Abstract: A keyboard structure of a portable computer, in which the keyboard is divided by a dividing line into two separate keyboard divisions which can be pivoted apart about a pivot center of the top end of the dividing line. Two supporting rods which are pivotally connected to each other are respectively disposed on bottom sides of the keyboard divisions. Two thread guide blocks are respectively pivotally connected to outer ends of the supporting rods and fitted around opposite thread sections of the thread rod. By means of directly shifting apart the keyboard divisions, the thread guide blocks are driven to rotate and slide toward two ends of the thread rod. When the thread guide blocks rotate, the connecting portion of the supporting rods is gradually lifted, whereby when the keyboard divisions are stretched apart, the rear end of the keyboard is also lifted by a certain inclination angle to facilitate the operation of an operator.
