Abstract: A control method for bi-stable displaying is provided, using queues for storing coordinates to achieve pipeline parallel processing on display data, thereby increasing display speed. In a preceding stage of the display process, because a plurality of queues may be used for temporarily storing part of the display data which is then reconstructed into complete display data to update a current frame buffer, comparing pixel data and generating driving data can be simultaneously preformed upon a plurality of line segments. Moreover, in a succeeding stage of the display process, a similar process may be performed to update a previous frame buffer, so access time can be reduced and errors caused by overlapping image blocks can also be avoided. Furthermore, the method may be also applied to a timing controller and a bi-stable display device.

Abstract: A back light boost converter includes an analog circuit, an enable controller, a logic device, and a digital PWM controller. The analog circuit generates a switch signal and a feedback signal based on a first pulse signal. The enable controller generates an enable signal based on an LED on ratio signal, an LED on cycle signal, a duty cycle signal, and a frequency signal. The logic device generates a second pulse signal based on the feedback signal and the enable signal. The digital PWM controller outputs the first pulse signal with increasing duty cycles in a plurality stages.

Abstract: A driving method adapted to a bistable display including a display panel is provided. The driving method includes following steps. A first area data and a second area data respectively received are sequentially stored in a first queue and a second queue, respectively. A first area image corresponding to the first area data and a second area image corresponding to the second area data are sequentially calculated. The first area image is displayed on the display panel during a first frame period of a first period, and the second area image is displayed on the display panel during a second first frame period of the first period. After the first period, the first area image on the display panel is in a stable state. After a summation time of first period and the second frame period, the second area image on the display panel is in a stable state.
