Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model based on the better embodiment of the all-in-one of surround lighting dynamic adjustments liquid crystal display backlight illumination.
Fig. 2 is the circuit diagram of the utility model based on backlight drive module in the all-in-one of surround lighting dynamic adjustments liquid crystal display backlight illumination.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1, the utility model relates to a kind of all-in-one based on surround lighting dynamic adjustments liquid screen backlight illumination, comprises display screen, TV motherboard, computer main board, light sensor, main control chip, backlight drive module and supply module; The VGA output interface of computer main board or HDMI output interface are electrical connected with the VGA input interface of television module or HDMI input interface respectively, and TV motherboard and display screen are electrical connected; Backlight drive module and display screen are electrical connected the backlight illumination regulating display screen; Light sensor and backlight drive module are all electrical connected with main control chip, and light sensor is used for the change of ambient light with the signal that changes, and variable signal is transferred to main control chip to control the duty of backlight drive module; Supply module is used for for display screen, TV motherboard, computer main board, light sensor, main control chip and backlight drive module for power supply.
Its concrete principle of work is; light sensor is for detecting the brightness of surrounding environment light; and produce corresponding electric signal by the change of surround lighting; and this electric signal is sent to main control chip; main control chip according to this electric signal to control backlight drive module work; backlight drive module then correspondingly controls the backlight illumination of display screen and the brightness of display screen and surround lighting is adapted, thus realizes the automatic adjustment of brightness of display screen in all-in-one, thus the eyes of protection people.Light sensor is the device to ambient light sensitive, can make a response to the change of ambient light rapidly in time.
Meanwhile, the display screen of this all-in-one is connected with TV motherboard and computer main board, can realize the function simultaneously seeing TV and online.Wherein computer main board is also provided with USB interface and SATA interface, USB interface is for connecting wireless network card and camera, and SATA interface is for connecting computer hard disc.
Preferably, main control chip triggers backlight drive module by pulse width modulating signal (PWM) or regulated voltage signal.Pulse width modulating signal is for extinguishing or lighting the part light source in display backlight.Wherein light source can be LED.
Concrete, in fig. 2, main control chip can export a modulating pulse, and now electric capacity C1 starts discharge and recharge.At the end of electric capacity C1 charges, the base stage of NPN pipe Q1 is high level, now Q11 conducting, and LED negative electrode level is dragged down, and now, LED is luminous.Accordingly, at the end of C1 electric discharge, the base stage of NPN pipe Q1 is low level, and now Q1 closes, and LED negative electrode level is driven high, and now, LED extinguishes.In the present embodiment, by control LED extinguishing or light, realize the control to touch display screen backlight.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
