Abstract

The invention relates to an electronic book, in particular to an electronic book with a solar cell touchpad. The structure of a solar cell is combined with the structure of a capacitance type touchpad, the electronic book can be charged by solar energy, and the function of page turning can be achieved through the capacitance type touchpad. Upward page turning can be achieved by sliding the touchpad in the upward direction or the inclined upward direction at any position, and the downward age turning can be achieved by sliding the touchpad in the downward direction or the inclined downward direction at any position. In order to avoid misoperation, the touchpad only responses to gestures sliding in the upward direction and the downward direction and does not response to actionless touch or pure sliding in the left direction and the right direction, so that dependence on mechanical keys is reduced, and practicability of the electronic book is improved.

Description

A kind of e-book with the solar cell touch pad

Technical field

The present invention relates to a kind of e-book, relate in particular to a kind of e-book with the solar cell touch pad, it combines the structure of solar cell and capacitive type touch pad, can carry out solar recharging for e-book, can realize by capacitive type touch pad the function of page turning again, reduce the dependence to mechanical key.

Background technology

E-book is a kind of portable hand-hold electronic equipments, aims at the read books design, usually uses Electronic Paper (E-ink) as display screen.At present, e-book all is equipped with lithium battery, uses the power supply adaptor charging.E-book is once charged needs 4 hours at least.Due to Electronic Paper when showing substantially without power consumption, only power consumption when page turning is so e-book is once charged the available several days time in the normal reading situation.But long charge cycle also can cause the user often to forget charging, runs into the situation of electric weight deficiency when reading.Also need carry power supply adaptor and cable in addition when long-distance travel, comparatively inconvenience.

E-book generally uses mechanical key to realize page turning, can produce the situation of keys deactivation unavoidably after long-term the use.Realize the combination of capacitive touch screen and electronic paper screen at some up-to-date e-book products, by the specific region of touch screen, perhaps realized page turning by specific touch gestures.But the shortcoming of this mode makes the processing procedure of electronic paper screen become complicated, and cost is higher.Secondly finger is often pressed screen and can be produced stain, thereby affects reading effect.

Summary of the invention

In order to overcome the deficiency of existing e-book, the invention provides a kind of solar cell touch pad that uses on e-book, the structure of photovoltaic solar cell and capacitive type touch pad is combined, can be charged to e-book by sun power like this, can realize by capacitive type touch pad the function of page turning again, the dependence of minimizing to mechanical key, the serviceable life of increase e-book.Due to the non-luminous characteristics of electronic paper screen self, the reading needs of e-book is in well-lighted environment, so just can continue charging to e-book by photovoltaic solar cell when reading.Instant charging in having realized like this using.This e-book can be read on the road for a long time, substantially breaks away from the dependence to power supply adaptor.

Novel feature of the present invention also is: because the solar cell touch pad only needs the slip gesture of pointing single direction is made a response, thereby produce the page turning action, its inner transparent conductive film (ITO) need not the location, touch point to finger, so can only plate the grid line of X-direction.The bridge architecture of complexity when so just having avoided ITO plated film X-axis grid line and Y-axis grid line to intersect has greatly reduced the processing procedure cost of ITO plated film.In use, the user only needs the touch pad that slides on any position makes progress or be oblique, just can realize upwards page turning; Downward or oblique lower slider can realize downward page turning.For fear of maloperation, touch pad only to the user slide up and down the gesture reaction, and to actionless touch or simple horizontally slip reactionless.When user's handheld electronic book was in the normal reading posture, solar panel was arranged in the electronic paper screen below of e-book, and the thumb of both hands can easily touch touch pad like this.And when holding e-book, thumb touch pad tiltedly on or tiltedly lower slider also meet ergonomic designs.

Embodiment

Fig. 1 is the perspective view with the solar cell e-book.E-book in figure is common structure in the market.Upwards page turning machinery knob 3 and the machinery of page turning downwards knob 4 that the electronic paper screen 1 that wherein comprises the middle, e-book symmetria bilateralis are arranged.E-book below also have some other function buttons 5.Solar cell touch pad 2 is elongated, be arranged in electronic paper screen under.

Fig. 2 is the front elevation of e-book, and realizes the schematic diagram of page turning by the slip gesture at touch pad.As shown in FIG., hold e-book when both hands, when being the normal reading attitude, the thumb of left hand or the right hand can touch solar cell touch pad 2 comparatively easily.When finger obliquely or during upward sliding, touch pad sends upwards page turning signal to e-book; When oblique time of finger or down sliding, touch pad sends downward page turning signal to e-book.

Concrete triggering mode is with reference to figure 4, the electric signal schematic diagram that the slide schematic diagram of touch pad and ITO grid line detect.The X-that only is plated in touch pad due to grid line 4-5 is axial, so can only sense the axial touch signal along Y-.When finger position slides into 4-2 from 4-1 along oblique lower left, perhaps slide into 4-3 along oblique lower right, the electric signal 4-4 that the ITO grid line detects can move down, and will send the instruction of downward page turning to e-book like this.Upwards page turning is also above-mentioned similar.For fear of maloperation, static electric signal can not trigger the page turning action.

Below with reference to Fig. 3, the cross-sectional view of solar cell touch pad.The touch pad outermost layer is chemically reinforced glass cover plate 6, and thickness is between 0.5 ~ 1mm.Tempered glass also can be protected inner ITO and solar battery structure in addition in order to prevent the scuffing on surface.ITO grid line 7 directly is plated in the inside surface of glass cover-plate, and the side of grid line is parallel with the X-direction along touch pad, the horizontal direction when namely reading, and the width of grid line is 1 ~ 2mm, interval 1mm.ITO grid line outer side covers has silicon dioxide protective film 8, plays the protective effect to the ITO plated film.Be hot melt adhesion glued membrane (EVA) 9 below silicon dioxide protective film, then the below is photovoltaic solar cell sheet 10 and another layer EVA film 9.The photovoltaic solar cell here adopts common monocrystalline silicon or polycrystalline silicon battery plate, and the technique of EVA film by hot pressing is pasted the upper and lower surface of cell piece and, the protective effect of playing and insulating.Because the present transmitance of ITO plated film can reach more than 85%, and also has the interval between ITO plated film grid line, so on the almost not impact of opto-electronic conversion at solar battery sheet.
