Abstract
一种用于电子墨水显示器的压电型电写笔，它由自动圆珠笔(包括笔芯、笔套和按钮开关)和压电陶瓷组成，其中笔芯和压电陶瓷装入笔套中，压电陶瓷和笔芯上下接触连接。书写时，弹出笔芯，使笔尖轻轻在电子纸上划写，笔芯就给压电陶瓷一个压力，从而在压电陶瓷的两端产生正负电荷，因此在笔芯的笔尖上就会聚集静电荷，从而在笔尖附近激发一个20～200伏的静电场。这个静电场就可以驱动电子墨水来显示书写轨迹。这种笔结构简单，成本低廉，使用方便。
A piezoelectric type electric writing pen for electronic ink display, which is composed of automatic ballpoint pen (including pen core, pen case and button switch) and piezoelectric ceramics, wherein the pen core and piezoelectric ceramics are put into the pen case, and piezoelectric ceramics Connect with the refill up and down. When writing, pop out the refill, let the pen tip gently write on the electronic paper, and the refill will put pressure on the piezoelectric ceramic, thereby generating positive and negative charges at both ends of the piezoelectric ceramic, so the pen tip of the refill will be Accumulate electrostatic charges, thereby exciting an electrostatic field of 20-200 volts near the pen tip. This electrostatic field can drive electronic ink to display writing tracks. The pen has the advantages of simple structure, low cost and convenient use.
Description
The present invention relates to a kind of display drive apparatus that is used for electronic ink display, particularly a kind of electric writing pen of making driving power by piezoelectric (as piezoelectric ceramics, organic piezoelectrics).
At present, based on the electric ink display material flexible display---Electronic Paper is succeeded in developing.Electronic Paper is made at two-layer transparent organic film intermediate package electric ink, thus Electronic Paper have thin, soft, in light weight, be easy to carry and characteristic such as cheap; Electronic Paper is a reflective display, promptly passive luminescence type display, so Electronic Paper has characteristics such as the wide and environmental protection of high-contrast, visual angle; Electric ink has bistable state, so Electronic Paper has characteristics such as low-power consumption.Electric ink is made up of many microcapsules, and the microcapsules the inside includes liquid paint and many charged solid granulates.When not having electric field, microcapsules demonstrate the color of pigment; Under electric field action, charged solid granulates is poured into one side of microcapsules, thereby microcapsules demonstrate the color of particle; When applying reversed electric field, microcapsules demonstrate the color of pigment again, thereby reach the purpose of demonstration.
In the present prior art, what the display driver mode of Electronic Paper was with the most use is the circuit drives mode, for example the flexible display driver circuit of Lucent's development.These display driver circuit cost height, owing to there is such shortcoming, this type of drive is not widely used in actual product as yet.But utilize electric writing pen to drive in many aspects is very convenient and cheap, for example the electric writing pen of Xerox Corporation's development.But the tail end at these electric writing pens is associated with a lead, and the power supply of electric writing pen is common dc source.Very inconvenient when therefore, writing with such pen.
The purpose of this invention is to provide a kind of piezoelectric electric writing pen that is used for electronic ink display, it is not only simple in structure, with low cost, and meets people's writing style.
The object of the present invention is achieved like this: the piezoelectric of packing in the inner chamber of the common automatic ball pen of plastics.Piezoelectric and pen core are contained in the pen cap, and piezoelectric contacts up and down with pen core and is connected.Pen core is that metal material is made, and pen core can eject or the indentation pen cap by press button.When writing, click the cap for brush, pen core has just ejected, firmly allowing nib draw on display then gently writes, pen core is just given pressure of piezoelectric, thereby produce positive and negative charge at the two ends of piezoelectric, therefore will the static electricity gathered lotus on the nib of pen core, thus near nib, excite an electrostatic field.This electrostatic field just can drive electric ink and show handwriting trace.When not needing to write, click the cap for brush again, pen core is with regard in the indentation pen cap.
Because only need write display and just can make electric ink on the position of nib, demonstrate hand-written track with defeating, so the present invention meets people's writing style as writing usually gently.The present invention forms in the automatic ball pen transformation of common plastics, only is made up of automatic ball pen of plastics (comprising pen core, the pen cap, press button and other part) and piezoelectric, so simple in structure.
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is vertical section structure figure of the present invention.

The described electric writing pen of Fig. 1 is to transform to form on the basis of the common automatic ball pen of plastics.Electric writing pen comprises an automatic ball pen of common plastics (spring (2), a pen core (3), a rotating disk (5), a push rod (7), a pen cap (8) and a cap for brush (9)) and a piezoelectric ceramics (4).Piezoelectric ceramics (4) and pen core (3) are contained in the inner chamber of the pen cap (8).The lower end of piezoelectric ceramics (4) contacts up and down with pen core (3).
The pen cap (8) is the plastic material of insulation.
Piezoelectric ceramics (4) is of a size of Φ 7 * 15, piezoelectric coefficient g
33〉=2.5 * 10
-2Vm/N.
Pen core (3) is selected metal ball pen for use, and its external diameter is 3mm, and suitably clips one section at afterbody.The nib of pen core (3) is the cone of 30 degree, and the end of nib is inlaid with a bead (1).Bead (1) is a metal material, and bead (1) can rotate in nib, and the diameter of bead (1) is 0.05～2mm.The size of bead (1) has just determined the size of person's handwriting.Bead (1) is more little, and the lines of writing out are just thin more.
Use automatic ball pen the same with usual, in the time of need writing, press the cap for brush (9) of ball pen, the cap for brush (9) will move downward together with push rod (7), the wedge of push rod (7) will promote the wedge of rotating disk (5), thereby makes rotating disk (5) while move downward and rotate.Rotating disk (5) promotes piezoelectric ceramics (4) when moving downward and pen core 4 (3) moves downward, thereby pen core (3) compression spring (2) and pen core (3) expose the pen cap (8).Unclamp the cap for brush (9), just move upward, but because rotating disk (5) has rotated an angle, so rotating disk (5) just is directed to piece (6) and has blocked at the restoring force effect lower rotary table (5) of spring (2).The nib of pen core (3) has just exposed the pen cap (8) like this; When not needing to write, the cap for brush (9) of pressing ball pen again just can be in pen core (3) the indentation pen cap (8).
When writing, the most advanced and sophisticated bead (1) of pen core (3) is drawn on display gently and is write, pen core (3) is just given (4) pressure of piezoelectric ceramics, thereby the two ends at piezoelectric ceramics (4) produce positive and negative charge, therefore will the static electricity gathered lotus on the most advanced and sophisticated bead (1) of pen core (3), because the needle point effect will excite one 20～200 volts electrostatic field near nib.The size of electrostatic field voltage is regulated by the pressure of writing, and it is big more to write pressure, and voltage is big more.This electrostatic field just can drive electric ink and show handwriting trace.
In optimum implementation of the present invention, the piezoelectric modulus of piezoelectric ceramics (4) is the bigger the better, and like this, required to write pressure just very little, just can prevent that display from being scratched.The pen cap (8) is an insulating materials, can prevent that like this hand or other approach of electrostatic charge by the people from leaking.Pen core (3) is a conductive material, and like this, electrostatic charge just can focus on the nib.
