Example 1.
A display screen as shown in fig. 1 includes a display section 11, a luminance detection mechanism 12 for detecting luminance information of an environment where an air conditioner is located, and a control mechanism 13 having a function of storing and controlling display luminance of the display section 11. It should be noted that the control mechanism 13 is preset with a reference value of the display brightness of the display screen 1 under various environmental conditions.
In the present embodiment, the display portion 11 is capable of displaying the operating state of the air conditioner. The brightness detection means 12 can detect the brightness information of the environment where the air conditioner is located, and transmit the environment brightness information to the control means 13. The control mechanism 13 has a function of storing and controlling the display luminance of the display section 11.
Further preferably, the brightness detecting means includes optical and electrical devices such as a photoelectric cell, an amplifier, and the like.
Example 2.
The embodiment provides a method for controlling the brightness of a display screen, which is applied to embodiment 1, and the method includes the following specific steps:
step 1: starting the system, and judging whether a brightness detection mechanism 12 of the display screen 1 is started; if the display screen is not turned on, the display part 11 of the display screen 1 continuously outputs the display screen with preset fixed brightness. It should be noted that the display screen 1 controls the on or off of the brightness detection mechanism 12 by receiving an external signal; for example, whether the viewing function of the display screen 1 is turned on or off is controlled by a remote controller.
Step 2: judging whether the control means 13 stores therein the abnormal information of the luminance detecting means 12; if so, the display screen 1 continues to output at a fixed brightness. It should be noted that the abnormal information of the brightness detection mechanism 12 is generated when the brightness detection mechanism 12 fails before the display panel 1 is operated. With the arrangement, under the condition that the brightness detection mechanism 12 has a problem, secondary damage to parts in the brightness detection mechanism 12 caused by repeated detection is avoided, and meanwhile, the brightness adjustment process is simplified.
And step 3: when the control mechanism 13 does not store the abnormal brightness information, it is determined whether the ambient brightness L of the environment where the display screen 1 is located, which is acquired by the brightness detection mechanism 12, is within the preset range [ a, b ] of the display screen 1.
And 4, step 4: when the ambient brightness L is within the preset range [ a, b ], clearing the abnormal information of the brightness detection mechanism stored in the recording control mechanism 13, and outputting the abnormal information of the brightness detection mechanism by the display part 11 at the brightness preset in the display screen 1 or manually preset by a user;
and 5: judging whether the user adjusts the manual current output brightness; if the brightness is adjusted, the display screen 1 outputs the brightness after manual adjustment by a user, stores the relevant information of the adjusted brightness in the control mechanism 13, and then repeats the step 4; otherwise, directly repeating the step 4. It should be noted that, under the current ambient brightness L, if the control mechanism 13 already stores corresponding information, the original data is updated; if there is no corresponding data stored in the control means 13, the corresponding brightness information is recorded in the control means 13.
And 7: when the ambient brightness L is outside the preset range [ a, b ], preliminarily judging that the light sensing detection data of the light sensing detection mechanism 12 are abnormal, counting the duration t of the abnormal occurrence of the light sensing detection data, and judging whether the duration t of the abnormal occurrence of the light sensing detection data is less than a system preset threshold c;
and 8: when the duration t of the abnormal occurrence of the light sensing detection data is less than a preset threshold c of the system, repeating the step 3; when the duration t of the abnormal occurrence of the light sensing detection data is greater than the preset threshold c of the system, the display screen 1 is normally on, and then whether the ambient brightness L is within the preset range [ a, b ] of the system is judged again. It should be noted that, when the duration t of the abnormal occurrence of the light sensing detection data is greater than the preset threshold c of the system, it can be preliminarily determined that the brightness detection mechanism 12 has a fault, so that the display screen 1 is normally bright.
And step 9: if the ambient brightness L is within the preset range [ a, b ] of the system, repeating the step 4; if not, continuously counting the duration t of the abnormal occurrence of the light sensing detection data, and judging whether the duration t of the abnormal occurrence of the light sensing detection data is greater than a preset threshold e of the system;
step 10: if the duration t of the abnormal occurrence of the light sensation detection data is greater than a system preset threshold e, the control mechanism 13 stores the abnormal light sensation detection information, and the display part 11 displays the abnormal light sensation detection information of the brightness detection mechanism 12; otherwise, repeating the step 4. It should be noted that when the duration t of the abnormal occurrence of the light sensing detection data is greater than the preset threshold e of the system, it is determined that the brightness detection mechanism 12 has a fault; when the duration t of the abnormal occurrence of the light sensing detection data is less than the preset threshold e of the system, it is determined that the brightness detection mechanism 12 has no fault. By the arrangement, under the condition that the brightness detection mechanism 12 is normal, the brightness method of the display screen 1 is circulated, so that the brightness of the display can be adjusted in real time, and the comfort of the display screen 1 in the using process is improved. Under the condition that the brightness detection mechanism 12 breaks down, the display screen 1 is always bright, and stable output of the display screen 1 is guaranteed.
In this embodiment, when the display screen 1 has abnormal brightness information, the display screen 1 can be restored only by manual reset or repair.
In this embodiment, after the brightness abnormal information occurs, it is determined that the brightness detection mechanism 12 fails, and the display screen 1 displays with a certain constant brightness, so as to avoid the failure of the brightness detection mechanism 12, which may cause the display screen 1 to fail to work.
In this embodiment, the user may manually change the brightness of the display screen 1, and the display screen 1 records and maintains the brightness information set by the user in the control mechanism 13.
In this embodiment, the control mechanism 13 of the display screen 1 is preset with the brightness data of the display screen 1 corresponding to different ambient brightness levels.
