Abstract
The utility model discloses a kind of laser screen of Intelligent adjustment brightness, comprise at least two luminance sensors, the microprocessor be connected with luminance sensor, the image controller be connected with microprocessor and the laser imaging that is connected with image controller is shielded; Described microprocessor is for generating two-way pulse-width signal; Described image controller comprises contrast and controls and backlight control; Described laser imaging screen comprises the signal modulation circuit, lasing light emitter, the light beam image-forming module that are connected successively.The laser screen of the Intelligent adjustment brightness that the utility model provides, adopt intelligentized control method, reach efficiency and effect that manual shift hardly matches, effectively promote work efficiency, add display frame effect simultaneously, meet user security, comfortable viewing condition by automatic regulating lightness.
Description
Technical field
The utility model relates to a kind of laser screen of Intelligent adjustment brightness, belongs to laser screen imaging techniques field.
Background technology
Along with popularizing of giant-screen equipment, the application scenarios of laser screen also gets more and more, meeting room indoor, to outdoor electronic label field, but while bringing outstanding display effect for user, also bring light pollution to a certain extent, especially ambient room light is more weak, when outdoor night, obvious to the stimulation of human eye.Regulative mode main is at present manual shift, but manual shift cannot accomplish good balance to display effect, too increases human cost simultaneously.
Summary of the invention
Goal of the invention: in order to overcome above-mentioned deficiency, the utility model provides a kind of can passing through detect ambient light thus regulate laser to shield the method for brightness.
Technical scheme: for solving the problems of the technologies described above, the technical solution of the utility model is: a kind of laser of Intelligent adjustment brightness screen, comprises at least two luminance sensors, the microprocessor be connected with luminance sensor, the image controller be connected with microprocessor and the laser imaging that is connected with image controller is shielded; Described microprocessor is for generating two-way pulse-width signal; Described image controller comprises contrast and controls and backlight control; Described laser imaging screen comprises the signal modulation circuit, lasing light emitter, the light beam image-forming module that are connected successively.
As preferably, the quantity of described luminance sensor is four.
As preferably, described microprocessor is the single-chip microcomputer with PWM module.
As preferably, the top of described laser imaging screen is located at by described luminance sensor.
The course of work: luminance sensor is set on screen top, to by luminance sensor, ambient brightness numerical value is obtained to the light in screen front, thus export microprocessor to and carry out Data Comparison, two-way pulse-width signal is generated to image controller according to correlation data, contrast control is carried out on one tunnel, backlight control is carried out on one tunnel, carry out the compensation of image output brightness or the reduction of image output brightness after laser imaging screen accepts the control of image controller, the brightness of laser screen is reduced and allows user have more comfortable viewing effect.
Beneficial effect: the laser screen of the Intelligent adjustment brightness that the utility model provides, tool has the following advantages:
The utility model adopts multiple luminance sensor, ensures the accuracy and the work efficiency that read data, avoids one of them fault to cause normally working; Regulated by intellectuality, Digital Control, the output of employing two-way, carries out contrast and brightness controls simultaneously, reaches the incomparable efficiency of manual shift and effect, effectively promotes work efficiency; Add display frame effect simultaneously, meet user security, comfortable viewing condition by automatic regulating lightness.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of luminance sensor in the utility model.
Fig. 2 is the reading schematic diagram of luminance sensor in the utility model.
Fig. 3 is the utility model principle schematic.
Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model further.
As shown in Figure 1, two luminance sensors 1 are set on laser imaging screen top; As shown in Figure 2, luminance sensor 1 pair of laser imaging screen front light obtain ambient brightness numerical value.
The laser screen of Intelligent adjustment brightness as shown in Figure 3, comprises two luminance sensors, the microprocessor be connected with luminance sensor, the image controller be connected with microprocessor and the laser imaging that is connected with image controller is shielded; Microprocessor is the single-chip microcomputer with PWM module; Image controller comprises contrast and controls and backlight control; Laser imaging screen comprises the signal modulation circuit, lasing light emitter, the light beam image-forming module that are connected successively.Microprocessor generates two-way pulse-width signal to image controller, image controller is respectively used to contrast and controls and backlight control after accepting two-way pulse-width signal, laser imaging screen accepts control signal to lasing light emitter after signal modulation circuit modulation, and lasing light emitter exports and controls result to light beam image-forming module.
More specifically embodiment is: set regulated value in advance, when ambient light reaches 1000lux, luminance sensor exports microprocessor to and carries out Data Comparison after collecting environmental data, send corresponding control command to image controller according to correlation data and carry out the compensation of image output brightness, make laser shield brightness and improve and allow user also can image on recognition screen under the environment that brightness is higher; When ambient light reaches 100lux, in luminance sensor reading numerical values contrast microprocessor, numerical value produces corresponding control command and is sent to the operation that image controller carries out the reduction of image output brightness, the brightness of laser screen is reduced and allows user have more comfortable viewing effect.
The utility model effectively raises the attribute of product in environment, users'comfort, greatly strengthens this Total Product effect.
Above-mentioned embodiment, only for technical conceive of the present utility model and feature are described, its objective is to allow and is familiar with these those skilled in the art and can understands content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalents done by the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
