Detailed Description
The method, apparatus and system for adjusting brightness of a light emitting device of the present invention will be described in more detail in conjunction with the schematic drawings, in which preferred embodiments of the present invention are shown, it being understood that those skilled in the art can modify the invention described herein while still achieving the advantageous effects of the present invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is provided for the purpose of facilitating and clearly illustrating embodiments of the present invention.
Example one
As shown in fig. 1, a method for adjusting brightness of a light emitting device includes the following steps:
the light-emitting device is provided with an automatic brightness adjusting coefficient A;
setting a manual brightness adjusting coefficient B adjusted by the light emitting device;
and combining the brightness automatic adjustment coefficient A and the brightness manual adjustment coefficient B to obtain a real brightness coefficient C, and adjusting the brightness value of the light-emitting device according to the real brightness coefficient C.
That is, in this embodiment, the actual brightness coefficient C is divided into two parts, namely, an automatic brightness adjustment part and a manual brightness adjustment part, by setting the automatic brightness adjustment coefficient a and the manual brightness adjustment coefficient B respectively, and then the user can correspondingly adjust the manual brightness adjustment coefficient B according to the user's own needs, so as to obtain the actual brightness coefficient C required by the user, and the actual brightness of the light emitting device is obtained by combining the actual brightness coefficient C with a reference value, so that the customized use needs of different people are met, and the change of ambient light can be considered.
The reference value is a standard value preset in the light-emitting device.
Further, it should be noted that, when the initial value of the manual brightness adjustment coefficient B in the present embodiment is combined with the automatic brightness adjustment coefficient a, the brightness adjusted by the automatic brightness adjustment coefficient a should not be changed.
For example, in one embodiment, the method for generating the true luminance coefficient C includes: multiplying the brightness automatic adjustment coefficient A and the brightness manual adjustment coefficient B to obtain a real brightness coefficient C;
the initial value of the manual brightness adjustment coefficient B is set to 1.
For another example, the method for generating the true luminance coefficient C includes: adding the brightness automatic adjustment coefficient A and the brightness manual adjustment coefficient B to obtain a real brightness coefficient C;
the initial value of the manual brightness adjustment coefficient B is set to 0.
In summary, when the initial value of the manual brightness adjustment coefficient B is combined with the automatic brightness adjustment coefficient a, the brightness adjusted by the automatic brightness adjustment coefficient a is not changed, that is, when the automatic brightness adjustment coefficient a remains unchanged, the change of the real brightness coefficient C can be completed by adjusting the value of the manual brightness adjustment coefficient B, so as to meet the actual use requirement of the user on the brightness.
Specifically, when the brightness of the light emitting device needs to be adjusted manually, if the brightness of the light emitting device is improved, the manual brightness adjustment coefficient B is a positive value, otherwise, when the brightness of the light emitting device is reduced, the manual brightness adjustment coefficient B is a negative value.
It should be noted that, in this embodiment, the actual luminance coefficient C is not obtained by simply multiplying or adding the luminance automatic adjustment coefficient a and the luminance manual adjustment coefficient B, but is replaced by another formula or algorithm by referring to the values of the two, and the specific formula or algorithm is not described herein again.
In other embodiments, other factors affecting the actual luminance coefficient C may be added on the basis of the two factors, for example, when the user is shocked or stressed, the user may be reminded by changing the actual luminance coefficient C, which is not described herein in detail.
As shown in fig. 2, the method for generating the brightness automatic adjustment coefficient a includes the following steps:
arranging an induction device in the light-emitting device; and adjusting the brightness automatic adjusting coefficient A according to the induction parameters identified by the induction device.
Specifically, the sensing device is arranged as a photosensitive element; and adjusting the brightness automatic adjusting coefficient A according to the intensity of the ambient light identified by the photosensitive device, namely identifying the external light through the photosensitive device and adaptively adjusting the brightness automatic adjusting coefficient A through the intensity of the external light.
Wherein, the stronger the ambient light is, the larger the brightness automatic adjustment coefficient A is.
In other embodiments, different applications may also correspond to different manual brightness adjustment coefficients B, and in the mobile phone screen, for example, the document corresponds to the manual brightness adjustment coefficient B1, and the WeChat corresponds to the manual brightness adjustment coefficient B2, and the manual brightness adjustment coefficients B corresponding to the different applications do not interfere with each other, that is, the user may adaptively adjust the brightness according to the color degree of the program interface when using the mobile phone, so as to further meet the requirement of the user for customized use.
Specifically, when a user opens a text, the screen brightness can obtain the real screen brightness C under the current condition according to the combination of the brightness manual adjustment coefficient B1 and the brightness automatic adjustment coefficient A, and further the screen brightness is controlled to perform corresponding adjustment; when a user opens the WeChat, the screen brightness can obtain the real screen brightness C under the current condition according to the product of the brightness manual adjustment coefficient B2 and the brightness automatic adjustment coefficient A, and then the screen brightness is controlled to be correspondingly adjusted; similarly, when the user opens other programs, the user can set the brightness manual adjustment coefficient Bn by himself, thereby facilitating the self-defined adjustment of the brightness of different programs.
Example two
The present embodiment further provides a brightness adjusting apparatus for a light emitting device on the basis of the first embodiment, so as to combine manual adjustment and automatic adjustment of screen brightness, thereby enabling the screen brightness to meet the customized requirements of users and also to take into account the adjustment required by ambient light change.
Specifically, the light-emitting device brightness adjusting device comprises a manual brightness operation unit, an automatic brightness detection unit and a brightness adjusting unit.
The manual brightness operation unit and the automatic brightness detection unit are connected with the brightness adjustment unit.
The brightness adjusting unit is used for receiving the brightness automatic adjusting coefficient A and the brightness manual adjusting coefficient B generated by the automatic brightness detecting unit and the manual brightness operating unit and obtaining a real brightness coefficient C.
The brightness of the light-emitting device is divided into two parts for manual adjustment and automatic adjustment according to ambient light through the manual screen brightness adjusting module and the automatic brightness detecting unit, so that the self-adaptive adjustment function according to ambient light change is considered while the use requirements of a user are met, and the actual use requirements of the user are met.
