Abstract
The invention discloses an electronic display unit for a reader. The electronic display unit for the reader is provided with a light sensing unit, a liquid crystal panel, a single-color light emitting diode array and a brightness adjusting unit, wherein the light sensing unit senses the brightness of environment light; the single-color light emitting diode array is positioned below the liquid crystal panel; and the brightness adjusting unit is connected with the light emitting diode array. When the electronic display unit works, the light sensing unit transmits environment brightness signals acquired by detection to the brightness adjusting unit; and the brightness of the single-color light emitting diode array is changed automatically under the control of the brightness adjusting unit so as to conform to change of environment background light. By the technical scheme, the display brightness can be adjusted automatically according to the strength of the environment light; and moreover, by a human eye tracking technology, movement of eyeballs of a user can be detected effectively, then pages can be turned according to the movement of the eyeballs of the user, and the electronic display unit for the reader is quite convenient to use.
Description
Technical field
The present invention relates to a kind of reader electronic display unit.
Background technology
In internet society, reader has started a large amount of alternative traditionally on paper media, very big is convenient for people to utilize the time of fragmentation to read in one's spare time.But the brightness of electronic reader is very high, long-time viewing easily causes vision impairment.If watched in outdoor simultaneously, due to bias light strongly, often do not see content again.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of reader electronic display unit of development, have:
Experience the light perception unit of environmental light brightness; Liquid crystal panel; Be positioned at the single color LED array below liquid crystal panel; The brightness adjusting unit be connected with described light emitting diode matrix; During work, described light perception unit is sent to described brightness adjusting unit by detecting the ambient brightness signal obtained, and the single color LED array described in brightness adjusting unit controls changes brightness, the change of the bias light that conforms automatically.
Also have eye movement judging unit, this unit has the oculomotor camera of human body, Real Time Observation human body eye motion, judges to show that eyeball is at display unit four direction, i.e. direction of motion up and down; Have page turning unit, be connected with described eye movement judging unit, receive the eye movement direction drawn, the content controlling current display carries out page turning.
Described eye movement judging unit and described brightness adjusting unit communicate to connect, when eyeball not detected, judge that current readers is in non-read state, the brightness of described single color LED array drops to minimum by the brightness adjusting unit described in control.
Owing to have employed technique scheme, a kind of reader electronic display unit provided by the invention, can the intensity of environmentally light, automatic adjusting display brightness; Have employed tracing of human eye technology simultaneously, can effectively detect eyeball action, and then carry out page turning action, very convenient use.
Accompanying drawing explanation
In order to the technical scheme of clearer explanation embodiments of the invention or prior art, introduce doing one to the accompanying drawing used required in embodiment or description of the prior art simply below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is module of the present invention
Embodiment
For making the object of embodiments of the invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear complete description is carried out to the technical scheme in the embodiment of the present invention:
As shown in Figure 1: a kind of reader electronic display unit, has: the light perception unit experiencing environmental light brightness; Liquid crystal panel; Be positioned at the single color LED array below liquid crystal panel; The brightness adjusting unit be connected with described light emitting diode matrix; During work, described light perception unit is sent to described brightness adjusting unit by detecting the ambient brightness signal obtained, and the single color LED array described in brightness adjusting unit controls changes brightness, the change of the bias light that conforms automatically.
For the convenience of the users, ensure the continuity of reading, as a preferably embodiment, also there is eye movement judging unit, this unit has the oculomotor camera of human body, Real Time Observation human body eye motion, judges to show that eyeball is at display unit four direction, i.e. direction of motion up and down;
Have page turning unit, be connected with described eye movement judging unit, receive the eye movement direction drawn, the content controlling current display carries out page turning.
Further, in order to save power supply, described eye movement judging unit and described brightness adjusting unit communicate to connect, when eyeball not detected, judge that current readers is in non-read state, the brightness of described single color LED array drops to minimum by the brightness adjusting unit described in control.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
