When this control module 20 receives update instruction, when certain pixel (pixel) of the picture of this Electronic Paper unit 40 need to be updated, in fact this pixel might also carry out at present old update instruction.That is to say, when this pixel also when carrying out the renewal of present stage, but receive that another new instruction need upgrade (also might be when receiving another new instruction certainly, finish at present old instruction, then not in this discussion scope).Namely, the user does not want the picture of old instruction yet, and wants the picture of new update instruction.
For example this pixel is originally at GTG 0, and originally old instruction is to be varied to GTG 8.When being changed to GTG 2, but receive that a update instruction will change to GTG 12.That is to say that the user wants GTG 8 originally, but but do not want now GTG 8, and want GTG 12, but not yet finish to the instruction of GTG 8, only proceed at present GTG 2.With present existing technology, can only finish first the instruction that is varied to GTG 8 from GTG 0, then, could carry out the instruction that will change to GTG 12.Therefore, the picture of the electric paper apparatus of prior art changes and to seem quite slow, when especially going to carry out new instruction when wanting to abandon originally old instruction, must wait until that old instruction is finished could carry out new instruction.
Summary of the invention
In view of this, fundamental purpose of the present invention is to provide a kind of menu renewal method of fast electric paper apparatus.
For reaching above-mentioned purpose of the present invention, the invention provides a kind of menu renewal method of electric paper apparatus, be applied to electric paper apparatus, this electric paper apparatus comprises control module, Electronic Paper driver element and Electronic Paper unit, and this Electronic Paper unit comprises at least one pixel.The menu renewal method of this electric paper apparatus comprises: this control module is accepted the first update instruction, and this pixel is updated to the first object GTG by initial GTG; If this pixel is being carried out the renewal of this first update instruction and is being updated to middle GTG, and this control module is accepted the second update instruction when being updated to the second target gray scale, then this control module calculates this pixel and is updated to by this centre GTG and is updated to the required very first time of this second target gray scale after this first object GTG again, and calculates and this pixel is carried out restoring action restore second time of carrying out again this second update instruction to this initial GTG; And if should the very first time greater than this second time, then this control module is controlled this Electronic Paper driver element this pixel is carried out carrying out this second update instruction after this restoring action again.
As can be seen from the above technical solutions, prior art is when receiving update instruction, and only can wait for that old instruction is finished just can carry out new instruction.And the present invention can calculate first and to restore that to carry out update instruction to GTG originally very fast again, still keeps originally to wait for and be finished old instruction just to carry out new instruction very fast.If it is very fast that first recovery to script GTG carries out update instruction again, then restoring extremely, the script GTG carries out update instruction again; If keep and originally wait for and be finished old instruction just to carry out new instruction very fast, then keep script and wait for that old instruction is finished and just carry out new instruction.Therefore, the menu renewal method of electric paper apparatus of the present invention will be more quicker than prior art, improve the picture pace of change of electric paper apparatus.
