Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the described Electronic Paper reader of present embodiment comprises Main Control Unit 1, and the operation embedded system program is as systems such as wince, built-in Linuxes; Electronic Paper display unit 4 and drive circuit unit 5 thereof are used for contents such as display frame; Be embedded in the lighting unit 2 in the Electronic Paper reader, for the Electronic Paper reader provides illumination; Storage unit 6 contains Flash and internal memory, and Flash is Nand Flash or NOR Flash, in save as SDRAM, DDR, DDRII, but be not limited to SDRAM, DDR, DDRII; Power Management Unit 8 is the power supply of Electronic Paper reader; Communication interface unit 7 is as SD card reader, USB interface, external power interface, by building an embedded platform, for Electronic Paper reader and the external world setting up communication; Brightness control unit 3 is regulated the brightness of lighting unit.
Described lighting unit is arranged on the upside or the both sides of Electronic Paper reader display unit, is made up of light emitting diode and light balanced device, and described light emitting diode is fixed on the light balanced device.Light emitting diode is at least 1, can provide the illumination of Electronic Paper reader required brightness, and low in energy consumption, helps environmental protection.But light emitting diode is a pointolite, and the light of emission is quite dazzling, and brightness was even inadequately when pointolite was radiated on the Electronic Paper reader.For this reason, the light balanced device that the lighting unit of present embodiment provides is exactly that pointolite with light emitting diode becomes area source, and the light of the diode of autoluminescence in the future evenly scatters on the Electronic Paper display unit, and it is very soft that light just becomes.
Described Power Management Unit is accumulator or rechargeable battery, is lighting unit and Main Control Unit power supply.Described brightness control unit for being arranged on the physical button on the Electronic Paper reader, also can be a scroll bar, by button or touch scroll bar, regulates the illumination brightness of lighting unit.
As shown in Figure 2, be the schematic appearance of present embodiment Electronic Paper reader.Among this figure, lighting unit 2 is arranged on the upside that Electronic Paper display unit 4 is an electronic-paper display screen, and 9 is the shell of Electronic Paper reader, and 10 is the keyboard region of Electronic Paper reader.Need to prove that this figure is a synoptic diagram, the every part among the figure is not limited in position shown in this figure, but can arbitrarily adjust as required, can be as lighting unit in both sides or other positions of shell, and keyboard region also can be in the left and right sides; Every part neither be requisite among the figure, can increase and decrease, and can remove as keyboard region.In addition, various piece shown in this figure also is not limited only to the quantity shown in this figure, can be more than one as lighting unit.
Fig. 3 is the horizontal section synoptic diagram of present embodiment lighting unit.Among the figure, light balanced device 21 is made by transparent optical material, as acrylic etc.And on physical arrangement, the light balanced device is spatial structure, as regular structures such as a flat cube and the non-regular texture that satisfies the brightness needs.Stamp circular or square diffusion point in the inboard of light balanced device with screen painting, described diffusion point employing possesses the high emissivity and the material of extinction not, spreads light with this.Light emitting diode 24 is close to the setting of light balanced device, and the wick 23 of light emitting diode also is to be close to the light balanced device.
When the irradiate light of light emitting diode during to the diffusion point, the diffusion white light that light emitting diode sends of naming a person for a particular job reflects to all directions, destroys conditioned reflex then and makes light penetrate from the light balanced device is positive.For light is evenly distributed, spread the not of uniform size of point, the density difference, roughly the same to guarantee light to the probability of all directions reflection.
Fig. 4 is the longitudinal sectional drawing of present embodiment lighting unit.Among the figure, 21 is the light balanced device, and 22 are the diffusion point; 24 is light emitting diode; 25 is reflectorized material; 26 are the casual mating plate of optics.Towards the casual further diffused ray of mating plate of a side attachment optics of Electronic Paper display unit, make that the light of lighting unit emission is more all even soft at the light balanced device.If the light that lighting unit sends is enough bright, can remove diffusion disk.The direction of arrow is that light penetrates direction, the i.e. position at light directive electronic-paper display screen place among the figure.Need to prove that except a side of the casual mating plate of placement optics and the surface of contact of light emitting diode and light balanced device, other side of light balanced device covers the reflectorized material of white.Its effect is the light reflected back light balanced device that the side is spilt, and to improve the utilization rate of light, increases brightness.
In order to protect Electronic Paper reader lighting unit of the present invention, an available firm protective cover covers lighting unit, only exposes the one side of light balanced device towards electronic-paper display screen.
In addition, present embodiment also comprises one and touches control module, as the hand-written module of electromagnetic type, capacitance touch module or resistive touch module, also can comprise keyboard input module, to be user-friendly to.Described touch control module is close to the setting of Electronic Paper display unit.
Electronic Paper reader provided by the invention has effectively overcome the Electronic Paper reader can not active illuminating and can't be at light than the problem of using under the dark situation, under the condition of extraneous insufficient light or dark, this reader is by opening lighting unit, for display screen provides illumination, can also adjust the power of light according to user's demand.The light that the lighting unit of this reader sends is soft, helps vision protection, and power consumption is very low, energy-conserving and environment-protective.
