Abstract
The invention discloses a display screen of an automobile navigator. The display screen of the automobile navigator comprises a light sensing unit, a liquid crystal display panel, a colored light-emitting diode array, a brightness adjusting unit, a camera and a control unit, wherein the light sensing unit is used for sensing the brightness of ambient light; the colored light-emitting diode array is positioned below the liquid crystal display panel; the brightness adjusting unit is connected with the light-emitting diode array; the camera is arranged above an interior reflective mirror, and is used for detecting actions of the eyes and the head of a driver and acquiring action videos of the eyes and the head of the driver. When the automobile navigator works, the control unit judges whether the driver is looking at the display screen of the automobile navigator through detection and analysis on the action videos of the eyes and the head, if the fact that the driver is looking at the display screen is detected, the brightness adjusting unit is controlled to increase the brightness of the colored light-emitting diode array, and if the fact that the driver is not looking at the automobile navigator is detected, the brightness of the colored light-emitting diode array is reduced.
Description
Technical field
The present invention relates to a kind of auto navigation display screen.
Background technology
Along with constantly popularizing of embedded navigation, increasing vehicle starts to install embedded navigation, in process easy to use, also bring corresponding problem, such as: in night running process, the brightness of display is too high, the normal line of sight of driver can be disturbed, easily the normal form of interference.
Through investigation, most of driver is in normal driving process, and the most of the time can not pay close attention to navigator display, only can listen the voice message of navigating and sending.Only just can start in difficult section to pay close attention to display screen.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of auto navigation display screen of development, have: the light perception unit experiencing environmental light brightness; Liquid crystal panel; Be positioned at the color light-emitting diode array below liquid crystal panel; The brightness adjusting unit be connected with described light emitting diode matrix; Arrange above in-vehicle reflection mirror, detect the camera of driver eye and headwork, gather driver head and eye motion video; And control module; During work, described control module analyzes the action video of described head and eye by detecting, judge whether driver is paying close attention to auto navigation display screen, and driver pays close attention to if detect, then control the brightness that described brightness adjusting unit heightens described color light-emitting diode array; If detect, driver does not pay close attention to auto navigation, then reduce the brightness of described color light-emitting diode array.Also there is light perception unit, detect surrounding enviroment monochrome information; During work, light perception unit is sent to described brightness adjusting unit by detecting the ambient brightness signal obtained, and the color light-emitting diode array described in brightness adjusting unit controls changes brightness automatically.
Control module detects the content of current display, from described database, transfer automatic regulation scheme, combining environmental brightness, changes the brightness of screen, contrast and color saturation, the change of conform bias light and displaying contents.
Owing to have employed technique scheme, a kind of auto navigation display screen provided by the invention, according to the concern of video analysis driver, when driver pays close attention to navigator display, just opens display, at ordinary times in form process, is substantially in closed condition.When not affecting driver sight, electric energy can also be saved.
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 map 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 auto navigation display screen, has: the light perception unit experiencing environmental light brightness; Liquid crystal panel; Be positioned at the color light-emitting diode array below liquid crystal panel; The brightness adjusting unit be connected with described light emitting diode matrix; Arrange above in-vehicle reflection mirror, detect the camera of driver eye and headwork, gather driver head and eye motion video; And control module; During work, described control module analyzes the action video of described head and eye by detecting, judge whether driver is paying close attention to auto navigation display screen, and driver pays close attention to if detect, then control the brightness that described brightness adjusting unit heightens described color light-emitting diode array; If detect, driver does not pay close attention to auto navigation, then reduce the brightness of described color light-emitting diode array.
Meanwhile, when driver pays close attention to display screen, in order to ensure that pipeline does not stimulate human eye, also there is light perception unit, detecting surrounding enviroment monochrome information; During work, light perception unit is sent to described brightness adjusting unit by detecting the ambient brightness signal obtained, and the color light-emitting diode array described in brightness adjusting unit controls changes brightness automatically.
Simultaneously in order to for different displaying contents, regulate most suitable display brightness, as a preferably embodiment, control module detects the content of current display, automatic regulation scheme is transferred from described database, combining environmental brightness, changes the brightness of screen, contrast and color saturation, the change of conform bias light and displaying contents.
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.
Claims (3)
