Abstract
The utility model relates to an electronic reader capable of detecting intensity of a light source, which comprises a main chip, an electronic paper display screen controller, an electronic paper display screen power module and an electronic paper display screen. The electronic paper display screen controller is connected with the main chip, and the electronic paper display screen power module is connected with the electronic paper display screen controller. The electronic reader is characterized in that the main chip is additionally provided with an electro-optical conversion module and a photosensitive device which are sequentially connected with the main chip. The electronic reader has the advantages that after the electronic reader appears on the market, the flicker-free and non-radiative electronic paper display screen with ultra-low power consumption are favored by many people, the electronic reader is more humanized if added with a light source intensity detecting function so that people can select a suitable environment to read, and then the electronic reader can protect eyesight of people better and assists people to form a good reading habit.
Description
Technical field
The utility model belongs to electronic reader, relates in particular to a kind of electronic reader that can detection light source intensity.
Background technology
It is target to replace paper market that electronic reader is commonly called as e-book, has the meaning of reform information obtain manner again, possesses the very strong market competitiveness.Simultaneously, along with the pay attention to day by day of the whole world to environmental protection, collection low power consumption, advantage such as frivolous, portable become the developing new focus of IT industry gradually.
The Electronic Paper that electronic reader adopts is different from our common fibrous paper, and it is a kind of display device with electric field driven, and the material that it is used to show mainly is " electronic ink " and " microcapsules ".Electronic ink is a kind of liquid, can print or be applied to any carrier surface, by two kinds of particle suspensions of very small black and white in transparency liquid and form.Microcapsules technology is wrapped in electronic ink in the microcapsules exactly, thereby has solved the rendezvous problem of pigment particle.The ultimate principle of Electronic Paper is: the capsule particulate that injects electronic ink has electric charge, and white particles has positive charge, and black particle has negative charge.When superincumbent battery lead plate top applies a negative electric field, the white particles that has positive charge will attracted to battery lead plate place under effect of electric field, assemble there, make battery lead plate place display white, simultaneously, the black particles that has the positive charge bottom of being ostracised under electric field action stashes.Otherwise, when applying a positive electric field on the superincumbent battery lead plate, then show black.Hence one can see that, and electronic reader does not have the backlight part, the same with common books, and we need under the irradiation of light source externally, could reading electronic book.So, just suitable reading when how much external light source intensity is? present electronic reader is not all indicated the function of external light source intensity.Need to be resolved hurrily on the market e-book of external light source intensity prompt facility to satisfy the demand that the reader selects suitable school environment, helps to form good reading habit.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of electronic reader that can detection light source intensity is provided, photosensitive device is installed on e-book, can experience the intensity of external light source, and be converted to electric signal and be input to master chip, master chip can judge this moment, whether light source suited to read, and the light source grade that shows this moment on screen (extremely secretly is not suitable for, darker, be fit to, brighter, incandescent is not suitable for), point out the reader to select the school environment that suits, help to form good reading habit.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of electronic reader that can detection light source intensity, comprise master chip and connected electronic-paper display screen controller, the electronic-paper display screen power module and the electronic-paper display screen that are connected with the electronic-paper display screen controller is characterized in that: described master chip is set up and its photoelectric conversion module that is connected successively and photosensitive device.
Beneficial effect: since the electronic reader listing, its flicker free, radiationless, favor that electronic-paper display screen super low-power consumption has been subjected to a lot of people.If add the function of detection light source intensity, make its more hommization, allow the reader select the adapt circumstance reading, better protection reader's eyesight helps the reader to form good school environment.
Description of drawings
Fig. 1 is the connection block diagram that increases the light source detection function;
Fig. 2 is the principle of work block diagram;
Fig. 3 is electronic-paper display screen display light source strength grade figure.
Embodiment
Below in conjunction with preferred embodiment, details are as follows to embodiment that foundation the utility model provides.
See accompanying drawing 1-3 for details, a kind of electronic reader that can detection light source intensity, comprise master chip and connected electronic-paper display screen controller, the electronic-paper display screen power module and the electronic-paper display screen that are connected with the electronic-paper display screen controller, described master chip are set up and its photoelectric conversion module that is connected successively and photosensitive device.
The APDS-9008 ambient light sensor (comprising photosensitive device and photoelectric conversion module) that can use Avago Technologies (Avago Technologies) to release, it can detect the situation of surrounding environment brightness, and is converted into analog electrical signal.Certainly, also have much other models, all be fine.
Principle of work:
See accompanying drawing 2 for details, photosensitive device is installed in front in e-book, can experience the intensity of external light source, and be converted to electric signal and be input to master chip, the AD conversion unit of master chip is a digital signal with electrical signal conversion, digital signal process data processing unit analyzes the strength grade of external light source this moment, and judges this moment, whether light source suited to read.At last, by the electronic-paper display screen control module, on electronic-paper display screen, demonstrate the intensity of light source grade of this moment.See Fig. 3 for details, electronic-paper display screen display light source strength grade illustrates, and may be displayed on the upper right corner of electronic-paper display screen.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (1)
