Embodiment Construction

[0080] Please refer to Figure 5, which is a schematic block diagram of a basic structure of a display control device according to an embodiment. The display control device 500 can be used in a bistable display device to control a bistable panel (not shown) to display data. In the display control device 500 of this embodiment, queues (Queues) temporary storage and data reconstruction technologies are used in the front stage of display, so as to increase the display speed of pen drawing or handwriting.

[0081] Such as Figure 5 As shown, the display control device 500 includes at least a timing controller 502 , a memory 504 and a lookup table 508 . The timing controller 502 is used to control the timing of all inputs and outputs, and is connected to a central processing unit (not shown) via a host interface 512 for receiving image data. In addition, the timing controller 502 is connected to the driving circuit for driving the bistable panel through the display interface 514...

Abstract

The invention discloses a bi-stable display control method. Displaying data are processed in a pipeline-type way parallel by using coordinate queues, so that the display speed is increased. At the front display stage, a plurality of queues can be used for temporarily storing a part of display data and remaking integral display data again to update a current frame buffer memory, so that comparison of pixel data on multiple line sections can be performed at the same time and a production flow of the data is driven. In addition, at the back display stage, a previous frame buffer memory can be updated by a similar way, so that an error caused during block image overlap is avoided while the access time is saved. The method can be applied to a time sequence controller and a bi-stable display device.

Description

technical field [0001] The present invention relates to a bistable display control technology, in particular to a bistable display control method that adopts a queue structure to improve display speed and quality, as well as a timing controller and a display control device using the method. Background technique [0002] In terms of current display technology, in addition to the large-scale display technologies generally used in households or end consumers, such as liquid crystal displays, plasma displays, or traditional image tube TVs, flexible display technologies using new-generation materials, There is also a trend of increasing attention. Among the current display technologies, besides the organic light-emitting diode (OLED) display technology, the bistable display technology has attracted the most attention. It has been widely used in e-book technology and continues to develop, intending to become a new alternative to paper in the future. A generation of flexible displ...
