Example

[0039] See figure 1 , The first embodiment of the backlight control method of the remote controller of the present invention is proposed. The backlight control method includes the following steps:

[0040] Step S101: Detect the light intensity of the current environment, and convert the light intensity into an AD value.

[0041] In this step S101, the light intensity of the current environment is detected in real time, and the light intensity is converted into an AD value through AD (analog to digital conversion) conversion.

[0042] Step S102: After detecting the key trigger signal, compare the AD value with a preset threshold value.

[0043] In this step S102, when the user presses a button on the remote control, the remote control will detect the key trigger signal, and immediately compare the AD value with the locally stored preset threshold value to determine the current environment light Strong or weak, and then turn on the backlight with the corresponding duty cycle. When the ...

[0055] See figure 2 , A second embodiment of the backlight control method of the remote controller of the present invention is proposed. The backlight control method includes the following steps:

[0056] Step S201: Detect the light intensity of the current environment, and convert the light intensity into an AD value.

[0057] In this step S201, the light intensity of the current environment is detected in real time, and the light intensity is converted into an AD value through analog-to-digital conversion.

[0058] Step S202: After detecting the key trigger signal, compare the AD value with a preset threshold value.

[0059] In this step S202, when the user presses a button on the remote control, the remote control will detect the button trigger signal, and immediately compare the AD value with the preset threshold value to determine the light intensity of the current environment. Then turn on the backlight with a corresponding duty cycle. When the current environment light is str...

Abstract

The invention discloses a remote control, and a backlight control method and a backlight control system thereof. The backlight control method includes steps: detecting illumination intensity of current environment, and converting the illumination intensity into an AD (administrative distance) value; after a button triggering signal is detected, comparing the AD value with a preset threshold valve, and turning on backlight with corresponding duty ratio according to comparison results; and after the backlight is turned on with the corresponding duty ratio for a preset time period, turning off the backlight. Control on backlight brightness according to the illumination intensity of the current environment is realized, the backlight brightness is lowered when the illumination intensity of the current environment is high, and the backlight brightness is increased when the illumination intensity of the current environment is low, so that electricity consumption is effectively lowered, and more humanization and intelligentization are realized.

Description

technical field [0001] The present invention relates to the technical field of remote controllers, in particular to a backlight control method and a backlight control system for a remote controller, and a remote controller with the backlight control system. Background technique [0002] Existing remote controllers are usually equipped with a backlight system. When the user triggers a button, the backlight system turns on the backlight, so that the user can clearly see the content on the display screen of the remote controller even in a weak or dark environment. The backlight source in the existing backlight system usually includes three LED lamps, and its rated current is as high as 20 milliamperes, and the power consumption is relatively large; and the backlight system of the existing remote control, no matter it is day or night, no matter the ambient light is strong Weak, once the user triggers the button, the backlight system will turn on the backlight with the same brigh...
