Description
Technical field
The present invention relates to a kind of display packing (display method) and electrophoretic display apparatus (electrophoretic display), particularly relate to a kind of display packing and the electrophoretic display apparatus that adopts above-mentioned display method that is applied to electrophoretic display apparatus.
Background technology
Fig. 1 illustrates the synoptic diagram of a kind of electrophoretic display apparatus of existing convention.See also shown in Figure 1; It is one non-volatile (promptly non-volatile that the electrophoretic display apparatus 100 of existing convention has; Hereinafter all is called non-volatile) storer (is memory body; Hereinafter all is called storer) (nonvolatile memory) 110, one volatibility (be volatility, hereinafter all is called volatibility) storer (volatile memory) 120, one processor (processor) 130, time schedule controller (timing controller) 140 and one electrophoretic display panel (electrophoretic display panel) 150.A plurality of data storing are in nonvolatile memory 110.
When the user wants on electrophoretic display panel 150, to watch wherein the time of these data; Processor 130 at first reads this data from nonvolatile memory 110; And these data are stored in volatile memory 120 via the bus (be bus-bar, hereinafter all is called bus) (not illustrating) of time schedule controller 140.Then, processor 130 is shown in electrophoretic display panel 150 by these data that time schedule controller 140 will be stored in volatile memory 120.When the user wanted on electrophoretic display panel 150, to watch other of these data, processor 130 read above-mentioned another data and then is presented at electrophoretic display panel 150 from nonvolatile memory 110 according to aforesaid way.
Fig. 2 is the diagrammatic cross-section that illustrates the electrophoretic display panel of Fig. 1.See also Fig. 1 and shown in Figure 2, electrophoretic display panel 150 has an electrophoresis layer 152, and it has a plurality of microcapsules (mi crocapsule) 152a and an electrophoretic fluid 152b who is filled in each microcapsules 152a.Electrophoretic fluid 152b in each microcapsules 152a comprises an insulation impregnant (dielectric solvent) 152c and a plurality of charged colored particles (charged pigment particle) 152d.These charged colored particles 152d intersperse among in the insulation impregnant 152c.The one side of each charged colored particles 152d is a white, and its another side is a black.
Yet, when the user wants in regular turn or backward when watching these data, processor 130 all must from nonvolatile memory 110 in regular turn or backward read these data, and in regular turn or backward be shown in electrophoretic display panel 150.In detail; The user from a certain data in regular turn or backward when being converted to another data, the user must wait for that processor 130 reads the time of (read out) nonvolatile memory 110, the time of processor 130 accesses (access) volatile memory 120 and the reaction time of electrophoretic display panel 150.Therefore, the electrophoretic display apparatus 100 of existing convention in regular turn or backward show that the T.T. of these data is longer.
This shows that above-mentioned existing application, obviously still has inconvenience and defective, and demands urgently further improving at method, product structure and use in the display packing of electrophoretic display apparatus and electrophoretic display apparatus.In order to solve the problem of above-mentioned existence; Relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly; But do not see always that for a long time suitable design is developed completion; And conventional method and product do not have appropriate method and structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of new display packing that is applied to electrophoretic display apparatus and electrophoretic display apparatus, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Because above-mentioned existing application is in the display packing of electrophoretic display apparatus and the defective of electrophoretic display apparatus existence; The inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge; And the utilization of cooperation scientific principle; Actively study innovation; In the hope of founding a kind of new display packing that is applied to electrophoretic display apparatus and electrophoretic display apparatus, can improve display packing and the electrophoretic display apparatus of general existing application in electrophoretic display apparatus, make it have more practicality.Through constantly research, design, and after studying repeatedly and improving, found out the present invention of true tool practical value finally.
