Example 1
As shown in fig. 1, the present embodiment provides a backlight adjusting system, which includes an ambient light sensor, a manual adjustment coefficient input module, a controller, and a light emitting device; the output ends of the ambient light sensor and the manual adjustment coefficient input module are respectively connected with the input end of the controller, and the output end of the controller is connected with the input end of the light-emitting element; the manual adjustment coefficient input module is used for selecting a manual adjustment coefficient; the controller is used for obtaining an automatic adjustment brightness value according to the signal acquired by the ambient light sensor and adjusting the brightness of the light-emitting element according to the product of the automatic adjustment brightness value and the manual adjustment coefficient.
Although the existing backlight adjusting system comprises automatic adjustment and manual adjustment, the two adjusting modes are independent, and in the automatic adjusting mode, a controller adjusts the brightness value of backlight according to the external brightness condition acquired by an ambient light sensor; in the manual adjustment mode, the human-computer interaction equipment acquires brightness input information and adjusts the brightness within the full range of brightness; the two adjusting modes are independent respectively, namely the ambient light sensor and the human-computer interaction device can be two control systems respectively. In the backlight adjusting system of this embodiment, the manual adjustment coefficient is input through the manual adjustment coefficient input module, the automatic adjustment brightness value is obtained through the signal acquired by the ambient light sensor, the product of the automatic adjustment brightness value and the manual adjustment coefficient is obtained through the controller, and the brightness of the light emitting element is adjusted. In this embodiment, the manual adjustment coefficient input module, the ambient light sensor, and the controller are integrated, and the controller needs to determine a final adjustment brightness value together with information of the manual adjustment coefficient input module and the ambient light sensor to adjust the brightness of the light emitting element, that is, the manual adjustment coefficient module can further adaptively adjust the brightness obtained by automatic adjustment, so as to better meet the requirement of the user on the backlight brightness.
Further, the manual adjustment coefficient input module described in this embodiment is a common input device such as a key, a touch screen, and the like; in this embodiment, the manual adjustment coefficient k input by the manual adjustment coefficient input module may be divided into 20 gears, and the coefficient k belongs to [0.05, 1.8], and the manual adjustment coefficient k is determined by selecting a gear through the manual adjustment coefficient input module, and an automatically adjusted brightness value obtained from a signal acquired by the ambient illumination sensor is changed to increase or decrease the automatically adjusted brightness value, so that a final brightness adjustment result may satisfy requirements of different users or different conditions for illumination. Meanwhile, the process of manual adjustment cannot influence the process of automatic adjustment, and the combination of the two adjustment modes enables the backlight adjustment mode to be more convenient.
Further, as shown in fig. 2, the backlight adjusting system further includes a PWM output module disposed between the controller and the light emitting element, and the light emitting element is an LED module. The controller adjusts the PWM value output by the PWM output module according to the product of the automatic adjustment brightness value and the manual adjustment coefficient so as to adjust the duty ratio of PWM and further adjust the brightness value of the LED module. The PWM adjusting mode is simple, and brightness adjustment of the LED backlight equipment is facilitated.
Further, the ambient light sensor is a photodiode. The ambient light value is collected through the photosensitive diode, and the scheme is simple and convenient to design and implement.
Further, the backlight adjusting system further comprises an AD collector, and the AD collector is disposed between the ambient light sensor and the controller. The AD collector converts analog signals collected by the photosensitive diodes into digital signals, and the controller can calculate and adjust brightness values conveniently.
Further, the light-emitting element is a DLP output module. If the automobile instrument adopts the image output mode of projection types such as ARHUD, the information display can be carried out by utilizing the DLP technology, the light-emitting element can adopt the DLP output module to carry out digital processing on the image signal and then carry out projection, and the brightness of the DLP output module is adjusted according to the product of the automatic adjustment brightness value and the manual adjustment coefficient.
