  • READING APPARATUS AND CONTROL METHOD THEREOF
    Publication number: 20170116905
    Abstract: A control method for a reading apparatus, includes making a display screen of the reading apparatus displaying a first pattern with a first gray value according to a first display request; and making the display screen displaying a second pattern with a second gray value according to a second display request under a condition of the first pattern existing. The second gray value is different from the first gray value.

  • Bi-stable display, frame updating method and timing control method thereof
    Patent number: 8446396
    Abstract: A bi-stable display, frame updating method and timing sequence controlling method thereof are disclosed. The frame updating method of the bi-stable display includes the steps of comparing a difference of source driver output voltages of adjacent frames of image updating period with a preset threshold, and determining parameter value of each transitional state of the adjacent frames when the difference equal or greater than the preset threshold for controlling level of source driver output voltage. Accordingly, the effects such as signal interference, reduction of image quality resulted from switching between high voltage levels directly and rapidly and excessive power consumption may be eliminated.
