Abstract
Disclosed is an electronic book light source compensating device. The electronic book light source compensating device comprises a protecting jacket (1) and a light-emitting device (2). The electronic book light source compensating device is characterized in that the protecting jacket (1) comprises a front cover (11) and a rear cover (12) connected to two parallel side edges of the front cover in a pivotal mode, the light-emitting device (2) is fixed on the inner side of the front cover (11), and the rear cover (12) is used for fixing an electronic paper display screen needing lighting; the light-emitting device (2) comprises a backlight source (22) and a luminance sensing device (23), wherein the backlight source (22) and the luminance sensing device (23) are connected with a microprocessor (21). After the front cover (11) of the protecting jacket (1) is opened, the luminance sensing device senses the luminance of the surrounding environment, and transmits the luminance value of the surrounding environment to the microprocessor (21), a minimum luminance value and a maximum luminance value are stored in the microprocessor (21), when the luminance value of the surrounding environment is smaller than the minimum luminance value, the microprocessor (21) outputs a starting control signal to enable the backlight source (22) to emit light, and when the luminance value of the surrounding environment is larger than the maximum luminance value, the microprocessor (21) outputs a stop control signal to enable the backlight source (22) to be closed. According to the invention, when the luminance of the surrounding environment is low, the light-emitting device emits light and irradiates an electronic book body, and thus a user can read a book normally.
Description
Technical field
The present invention relates to a kind of protective sleeve, specifically, be a kind of can be the protective device of e-book compensatory light.
Background technology
Electronic-paper display screen is a kind of display screen of reflection, and by AG film, electronic ink layer, glass substrate forms.Electronic-paper display screen utilizes electrophoretic display technology (EPD) principle to invent and forms, electrophoretic display technology (EPD) is be packaged in micella droplet structure by the charged particle of black, white dichromatism, the lifting moving of different electric charge black and white particle is controlled by extra electric field, to present the display effect of monochrome, under the effect of electric field, the particle that black and white two kinds is different is not stopped transport dynamic, when the particle of white rises to upper surface, all ambient lightings are mapped to upper surface and are completely reflected, material is thus formed the state of white, the namely state of paper; When after exchange electrode, the particle of two kinds of colors can switch, and particle white so just can to having gone below, and above the particle of black is arrived, light is all absorbed by the particle of black, and result just causes black, also just defines white and black displays.In addition, also can there is the state of mixing at upper surface, the mixing that two kinds of different particles are proportional, black and white can be formed like this and have the different colours of gray-level, because EPD technology can present the white and black displays effect of high reflectance, high contrast, therefore very applicablely do Electronic Paper.
What present e-book was most of is exactly electronic-paper display screen, and its shortcoming external light source must be relied on to throw light on could watch, and when external light source is lower time, e-book is just difficult to use.
Existing e-book protective sleeve does not have illumination functions.
Summary of the invention
The object of this invention is to provide a kind of e-book light source compensator, it can be e-book compensatory light when light source deficiency.
The present invention is by the following technical solutions: a kind of e-book light source compensator; comprise protective sleeve (1) and light-emitting device (2); it is characterized in that: described protective sleeve (1) comprises protecgulum (11) and is articulated in the bonnet (12) of the parallel lateral margin of protecgulum two; described light-emitting device (2) is fixed on protecgulum (11) inner side; bonnet (12) is for the fixing electronic-paper display screen needing illumination; after opening described protective sleeve (1); when the brightness of surrounding environment is lower, described light-emitting device (2) is luminous and be radiated on described electronic-paper display screen.
Described light-emitting device (2) comprises the backlight (22) and brightness impression device (23) that are connected with microprocessor (21), after opening the protecgulum (11) of described protective sleeve (1), described brightness impression device is responded to the brightness of surrounding environment and is sent the brightness value of surrounding environment to described microprocessor (21), described microprocessor (21) stores minimum brightness value and highest brightness value, when the brightness value of surrounding environment is less than described minimum brightness value, described microprocessor (21) exports startup control signal and makes described backlight (22) luminous, when the brightness value of surrounding environment is greater than described highest brightness value, described microprocessor (21) exports stop control signal and described backlight (22) is closed.
Further, described light-emitting device is also provided with the on-off switch (3) for controlling described backlight.
The invention has the beneficial effects as follows: compare prior art, luminous when the present invention is lower by the brightness of light-emitting device environment around, be radiated on e-book body, user can normally be read a book.
The present invention is a component invention, and its accessory can commercially or to manufacturer be had made to order.Each accessory is all that oneself knows technology above, and this description is no longer described in detail.
