Abstract
The utility model discloses an automatic display brightness adjustment and control device, which is characterized in that the device comprises a light sensor which is arranged on a display panel frame, the signal output end of the light sensor is electrically connected with an automatic adjustment signal generation module and the signal output end of the automatic adjustment signal generation module is electrically connected with a brightness control circuit. When the brightness of ambient light is changed, the light sensor which is arranged on the display panel frame can sense the change of the ambient light; when the ambient light becomes brighter, the automatic adjustment signal generation module sends out an automatic adjustment signal of brightening a display panel; when the ambient light becomes darker, the automatic adjustment signal generation module sends out an automatic adjustment signal of darkening the display panel; and the brightness control circuit brightens or darkens the display panel according to the received automatic adjustment signal.
Description
Technical field
The utility model relates to a kind of automatic brightness and controller, relates in particular to a kind of automatic brightness and controller that is applicable to display.
Background technology
For human eye is watched comfortable, need change the screen intensity of adjusting computer monitor according to the light intensity of environment, display on the market adopts the manual adjustments control knob that is arranged on the display lower right corner to control mostly at present, adjust very inconvenient, and manual shift is difficult to the screen of display is adjusted to optimum condition, and long-time use meeting damages eyesight.
The utility model content
Technical problem to be solved in the utility model provides a kind of automatic control set for adjusting of display brightness that can adjust indicator screen brightness automatically.
For solving the problems of the technologies described above, the technical solution of the utility model is: the automatic control set for adjusting of display brightness, comprise the light sensor that is arranged on the display panel frame, the signal output part of described light sensor is electrically connected with the self-regulated signal generator module, and the signal output part of described self-regulated signal generator module is electrically connected with the brightness regulation control circuit.
As a kind of optimized technical scheme, described self-regulated signal generator module comprises signal judging circuit.
As a kind of optimized technical scheme, described signal judging circuit comprises single-chip microcomputer.
Owing to adopted technique scheme, the automatic control set for adjusting of display brightness, comprise the light sensor that is arranged on the display panel frame, the signal output part of described light sensor is electrically connected with the self-regulated signal generator module, and the signal output part of described self-regulated signal generator module is electrically connected with intednsity circuit; When the light luminance of environment changes, be arranged on the variation that light sensor on the display panel frame is experienced ambient light, when ambient light brightens, the self-regulated signal generator module send lighten display panel from tonal signal; When the ambient light deepening, the self-regulated signal generator module send dim display panel from tonal signal; Intednsity circuit lightens or dims display panel according to what receive from tonal signal.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is a schematic block circuit diagram;
Among the figure: the 1-light sensor; 2-hand adjustment control knob; The 3-display panel; The 4-display panel frame.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only some one exemplary embodiment of the present utility model has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
As depicted in figs. 1 and 2, the automatic control set for adjusting of display brightness, comprise the light sensor 1 that is arranged on the display panel frame 4, the signal output part of described light sensor 1 is electrically connected with the self-regulated signal generator module, described self-regulated signal generator module comprises signal judging circuit, described signal judging circuit comprises single-chip microcomputer, the signal that single-chip microcomputer passes over according to light sensor 1, judge whether to lighten or to dim display panel 3, and according to judged result, send the control signal that lightens or dim display panel 3, this control signal is identical with the control signal that the hand adjustment control knob produces, can both be by existing manual brightness regulation control circuit identification in the prior art.The signal output part of described self-regulated signal generator module is electrically connected with the brightness regulation control circuit, described intednsity circuit is except the signal that is received from the tonal signal generation module, also receive hand adjustment control knob 2 and transmit the signal of coming, when the brightness regulation control circuit receives the conditioning signal of self-regulated signal generator module output, brightness according to this signal adjustment display panel 3 realizes automatic regulatory function; When the brightness regulation control circuit received the conditioning signal of hand adjustment control knob 2 generations, the brightness according to this signal adjustment display panel 3 realized the manual adjustments function; This intednsity circuit is identical with existing manual brightness regulating circuit in the prior art, repeats no more here.
Automatically regulate principle of work: when the light grow of environment brightens, light sensor is just sensed the strong and weak variation of light, and send signal, the single-chip microcomputer of self-regulated signal generator module receives the output signal of light sensor, and it is judged, the information of carrying according to signal, judge the strong and weak degree that changes of ambient light, and make output signal to the exponent number of display panel brightness regulation, be analogous to the pulse output number signal of hand adjustment control knob, the signal conveys of single-chip microcomputer output is given intednsity circuit, and the intednsity circuit response is heightened the brightness of display panel 3 or turn down.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
