Description
Technical field
The present invention relates to the electric ink screen technical field based on the Android system, particularly the electric ink based on the Android system shields the refresh control system and method.
Background technology
Android is former to be intelligence system for mobile phone development, only supports the demonstration of TFT screen.And the type of drive of TFT display screen is shown to the content in the video memory on the display screen by demonstration I/O interface then for will content displayed copying in the video memory.
But the type of drive of electric ink screen (Eink screen) is for behind the video memory content update, at first the content in the video memory is sent in the internal memory of chip controls, then, the rectangular area that CPU notice chip will show, and the notice chip refreshes the displaying contents in the respective rectangular zone of display panel with certain waveform pattern (DU or GC16).
DU and GC16 are wherein two kinds of waveform pattern (waveform mode), and DU supports 2 kinds of GTGs: black and white.GC16 then supports 16 kinds of GTGs.
As can be known, the rectangular area that each needs refresh can not be known in the Android system when showing more than the contrast, just displaying contents is deposited in the video memory, refreshes by showing that the I/O interface is controlled then, and in addition, it can not support the different wave pattern of electric ink.If support the electric ink screen with the former display mode of Android system, then system must refresh a whole screen at every turn, and all refreshing all is a kind of waveform pattern.And the display speed of electric ink screen does not wait to 1S from more than 30 ms according to rectangular area size that refreshes and pattern and the mode difference that refreshes at every turn.In this case, can not satisfy our demand to the quick rolling of high bright wisp in the list box.

Description of drawings
Fig. 1 is the process flow diagram of the embodiment of the invention;
Fig. 2 is the structural representation of the embodiment of the invention.
Embodiment
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Be illustrated in figure 1 as the concrete steps of the embodiment of the invention:
In the Android system, when refreshing view, then call the invalidate function, after calling invalidate, surface flinger can dispatch in system, surface flinger can copy present displayed content among the front buffer (being video memory) to from back buffer (region of memory of system assignment, size equals video memory), by the demonstration I/O interface among the CPU content among the front buffer is shown on the display screen then.
Therefore present embodiment adopts following steps:
Step S110, in the list box interface, when high bright wisp when a position is rolled to another position, two rectangular area coordinates of motion track are passed to surfaceflinger, surfaceflinger passes to driving to these two coordinates then, preserve these two coordinates in the lv_list variable in driving, and the refresh mode of these two coordinates is labeled as DU.
Step S120, when surfaceflinger begins processes and displays, at first the rectangular coordinates all dirty zones passes to driving in surfaceflinger, write down all these dirty rectangular area coordinates in the oth_list variable in driving, and the refresh mode of these rectangular area coordinates is labeled as GC16.
Wherein, DU is used for 2 rank gray scales, and promptly black and white, GC16 then supports 16 rank gray scales.Because DU only supports 2 rank gray scales, so it refreshes sooner than GC16, but only is suitable for refreshing some simple region, as the high bright wisp in the present embodiment.
Step S130, surfaceflinger copies present displayed content the front buffer to from back buffer.Surfaceflinger gives driving control then.
Step S140, in driving, at first judge whether node is arranged in the lv_list variable, if have, just begin to show the coordinate of all nodes in the lv_list variable, refresh mode is the refresh mode that writes down in the node, has shown behind all nodes in the lv_list variable all knot removals in this tabulation directly to be deleted all nodes in the oth_list variable then; If do not exist in the lv_list variable under the situation of node, begin to show the coordinate of all nodes in the oth_list variable, refresh mode is the refresh mode that writes down in the node, and having shown will be with all knot removal in this tabulation behind all nodes in the oth_list variable.After finishing dealing with, return then and finish this display operation.
Be illustrated in figure 2 as the structural representation of the embodiment of the invention.
Application layer 210 (Application) passes to ListView220 to relevant service data, ListView220 is by internal thread communication (Inter-process communication, IPC) mode passes to surfaceflinger thread 230, surfacefl inger thread 230 data transfer to driving in 240.
Electric ink screen refresh control system 241 based on Andro id system is arranged in the driving 240, and system 241 comprises:
Be used to store the memory module 2411 of whole screen image data, surfaceflinger to memory module 2411, is the oth_list variable to whole screen data transmission in the present embodiment;
Be used for refreshing the display module 2412 of the view data of output memory module 2411 to the electric ink screen;
Be used for extracting from system the regions module 2413 of specific region coordinate, surfaceflinger is stored in regions module 2413 to the specific region coordinate that obtains from ListView220, be lv_list in the present embodiment;
Be used for the detection module 2414 whether the detection coordinates module exists data:
If have data in detection module 2414 regions module 2413, then 2412 of display modules refresh the view data that output is determined by area coordinate;
If there are not data in the regions module 2413, then display module 2412 refreshes output all images data.
The above only is a preferred implementation of the present invention; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
