Problems solved by technology

The brightness and volume of various LED displays and LED displays are generally fixed values, or can also be adjusted manually, but due to the relatively large changes in ambient brightness and ambient sound, such as day and night, rainy weather and sunny days , the brightness of the environment and the size of the sound are very different, and manual adjustment will bring a lot of inconvenience, and the LED display or LED display with fixed brightness and volume is relatively large in energy consumption, which cannot better meet the characteristics of energy saving. Moreover, the audio-visual effect is relatively poor

Embodiment 1

[0024] Such as figure 1 As shown, this embodiment provides an LED display controller, the LED display controller is used to control the intensity of the brightness of each LED light-emitting unit in the LED display device, so that each LED light-emitting unit in the LED display device can be brightened and changed. Darkness and other display effects, and the LED display controller can also be used to control the volume of the LED display device. The LED display controller can be applied to displays of mobile phones, computers, cameras, televisions, and e-readers, etc., and the LED display controller can also be directly applied to LED display screens, and each LED light-emitting unit can be used as The backlight light source of each display can be used to directly display video animation, etc.

[0025] The LED display controller is provided with a receiving module, a brightness sensing unit, a brightness adjustment module, a volume sensing unit, an audio adjustment module, an...

Embodiment 2

[0032] Such as figure 2As shown, on the basis of the above examples, in the LED display controller provided by this embodiment, the brightness sensing unit and the volume sensing unit are set together in a sensing module, and the sensing module is respectively connected to the The brightness adjustment module and the audio adjustment module are connected, and the sensing module can also be integrated with the brightness adjustment module and the audio adjustment module, and fixed on the LED display device for Sensing the brightness of the surrounding environment of the LED display device and the volume of the surrounding environment, thereby generating the ambient brightness value and the ambient volume value.

[0033] As another example, the brightness sensing unit and the volume sensing unit can also be set separately, and are respectively connected to the brightness adjustment module and the audio adjustment module through lines, and the brightness sensing unit and the vol...

Embodiment 3

[0035] Such as image 3 As shown, on the basis of the above-mentioned examples, in the LED display controller provided in this embodiment, the LED display controller further includes one or more sensing switches, and the sensing switches are respectively connected to the brightness sensing unit, the volume sensing unit, the brightness adjustment module, and the audio adjustment module are connected.

[0036] The sensor control switch receives the ambient brightness of the brightness sensing unit and the ambient volume of the volume sensing unit, and when the ambient brightness is higher or lower than a certain fixed preset value , start the brightness adjustment module, generate brightness adjustment data, and adjust the display brightness of each LED light-emitting unit in the LED display device. At the same time, when the ambient volume is less than or greater than a certain fixed set value, Then start the audio adjustment module, generate volume adjustment data, and adjust...

Abstract

The invention discloses an LED display controller and an LED display device. The LED display controller comprises a receiving module, a brightness sensing unit, a brightness adjusting module, a volume sensing unit, an audio adjusting module and a controlling module; the receiving module receives audio signals and display signals; the brightness sensing unit is used for sensing surrounding environment brightness; the brightness adjusting module generates brightness adjusting data according to the environment brightness to adjust the display signals; the volume sensing unit senses the surrounding environment volume; the audio adjusting module generates voice adjusting data according to the environment volume to adjust the audio signals; the controlling module generates control signals according to the adjusted display signals and audio signals to control an external LED illuminating unit; and the controlling module is also provided with a storage sub module stored with preset control signals. The invention causes the audio-visual effect of the LED display device to be very good and is more environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to the field of LED display control, in particular to an LED display controller and an LED display device using the LED display controller. Background technique [0002] In the prior art, LED products are more and more popular among users due to their environmental protection and energy saving features, and at the same time, the application fields of LEDs are also becoming more and more extensive. [0003] In addition to being used in various lighting decorations for lighting decoration, LEDs can also be used in various displays, such as mobile phones, computers, TVs, cameras, electronic readers, etc. for backlighting, as well as various LED displays. Each LED is used to display video directly. The brightness and volume of various LED displays and LED displays are generally fixed values, or can also be adjusted manually, but due to the relatively large changes in ambient brightness and ambient sound, such as day and night, rainy ...
