Embodiment:
Electronic Paper is a kind of special paper, be coated with micro unit (being also referred to as pixel cell) on it with electrophoretic characteristic or electro-wetting property, these micro units have the externally following characteristic that changes optical states of electric field action, and after the optical states change, even remove extra electric field, still can keep optical states.Therefore, be actually control for the printing of Electronic Paper and be added in the external electrical field size and Orientation on each micro unit on the Electronic Paper, make each micro unit on the Electronic Paper present the optical characteristics of our needs.
Electronic Paper described in the present invention, itself do not have print or the metal electrode of electronization reducing the cost of Electronic Paper, but will print or the metal electrode of electronization all as the parts of Electronic Paper printing equipment.Therefore need print or electronization by the Electronic Paper printing equipment for the printing and the electronization of Electronic Paper.
In addition, because described Electronic Paper can be that the flexible material of paper material or other hope is as the substrate of thin plastics as Electronic Paper.Can make various Electronic Paper.
Further describe specific embodiments of the present invention below in conjunction with accompanying drawing.
Fig. 1 is the principle of work synoptic diagram of Electronic Paper printing equipment.The Electronic Paper printing equipment comprises at least as lower member: mechanical motion driving circuit 101, mechanical motion topworks 102, information control unit 103, gridding information storage unit 104, grid array driving circuit 105, grid array first electrode 106, grid array second electrode 108.Grid array first electrode 106 is placed with grid array second electrode 108 mutual opposites, places the Electronic Paper 107 that need print between grid array first electrode 106 and grid array second electrode 108.Annexation between each parts as shown in Figure 1.
Fig. 2 is the structure and the principle of work synoptic diagram thereof of information control unit.Fig. 2 plants the structure that has further provided information control unit, comprises central processing unit 232, character library unit 231, memory circuit 234, character font map unit 233.
The course of work of printing Electronic Paper is:
When being printed on Word message on the Electronic Paper, need information control unit to carry out the conversion process of character to dot matrix font, the Word message that at first needs is printed on the Electronic Paper 107 stores in the data back of memory bank circuit 234, program in the procedure stores body of central processing unit 232 operation memory circuits 234, utilize the character library information in the character library unit 231 that Word message is converted to dot matrix font information, store into then in the character font map unit 233, so that under the control of central processing unit 232, with the information translation of character font map unit 233 is grid electrode array 106, the information of voltage of 108 counter electrodes is sent to gridding information storage unit 104, import grid array driving circuit 105 into gridding information storage unit 104 canned datas then, thereby realize the printing of Electronic Paper.
When being printed onto on the Electronic Paper for image information, because image has been a pixel, irrelevant information transforms, can be directly with the pixel information stores of image in character font map unit 233, so that under the control of central processing unit 232, with the information translation of character font map unit 233 is that the information of voltage of grid electrode array 106,108 counter electrodes is sent to gridding information storage unit 104, import grid array driving circuit 105 into gridding information storage unit 104 canned datas then, thereby realize the printing of Electronic Paper.
In order to guarantee that grid array first electrode 106, grid array second electrode 108 are corresponding one by one with the corresponding net point of Electronic Paper, need to adjust the position of grid array first electrode 106, grid array second electrode 108, in Fig. 1, a kind of implementation is fixed mesh array second electrode 108, Electronic Paper 107 places the correct position of grid array second electrode 108, by information control unit 103 control mechanical motion driving circuits 101, position to the correct position of grid array first electrode 106 is adjusted in 102 motions of mechanical motion topworks.Mechanical motion topworks 102 adopts high precision stepping control motor usually, and high precision stepping control motor often uses in robot control field.In fact mechanical motion driving circuit 101 is controlled mechanical movement executing mechanism 102, thereby control is connected grid array first electrode 106 with the mechanical movement executing mechanism 102 of control by linkage assembly moves, can be designed as on the plane that X, Y direction constitute and do the two degrees of freedom controlled motion, also can be designed as on the solid that X, Y, Z direction constitute and do the Three Degree Of Freedom controlled motion, with the position of accurate control mesh array first electrode 106.The design of mechanical motion driving circuit 101 matches with the mechanical motion topworks 102 that is adopted, pulse voltage signal for the drive signal of above-mentioned stepper motor, corresponding mechanical motion driving circuit 101 need be according to grid array first electrode 106 current positions, calculate data such as moving to the needed potential pulse number, pulse width on each degree of freedom of correct position.In preferred design,, and positional information is fed back to mechanical motion driving circuit 101 realize that closed-loop controls are to improve positional precision at grid array first electrode 106 installation site sensing elements.And the logic realization of mechanical motion driving circuit 101, after can taking to calculate the result is delivered to mechanical motion driving circuit 101 or mechanical motion driving circuit 101 itself has certain computing ability or FPGA (Field Programmable Gate Array) ability, finish pulse parameter by mechanical motion driving circuit 101 and calculate by information control unit 103.About position transducer multiple mode is arranged, can finish the calculating of relative position or absolute position as global position system GPS or image acquisition analytic system or lodar etc.
The storage class of gridding information storage unit 104 is read-write memory banks, it has stored current the printing or the Electronic Paper information that need present of electronization, it is the optical states that each electronic unit need present in the corresponding Electronic Paper 107, and to finish the optical states of controlling each electronic unit in the Electronic Paper 107, need this information is become intensity, the direction that is applied to the extra electric field of each electronic unit in the Electronic Paper 107 by grid array driving circuit 105 and hold time.Therefore according to different grid arrays first electrode 106, grid array second electrode 108 method for designing differences, need to adopt corresponding grid array driving circuit 105.
When all being the electrod-array that constitutes by small electrode for grid array first electrode 106, grid array second electrode 108, being actually each electronic unit of realizing Electronic Paper independently controls, grid array driving circuit 105 becomes the information that the intensity that is applied to the extra electric field of each electronic unit in the Electronic Paper 107 and direction need present as required and calculates, because each electronic unit is independently controlled, do not need scanning, so the time of extra electric field can keep always, perhaps extra electric field is kept to be enough to change optical states and to reach and is removed extra electric field when stablizing.
