LED film screen is applied in the field of large-screen display advertising, cool and transparent images, helping the development of the media market. However, the background of LED film screen is too bright, which will also bring negative effects, such as visual fatigue caused by watching for a long time, and light pollution caused by outdoor display. So how to solve it?

At present, the brightness of the indoor LED film screen is about 1000cd/㎡, which can ensure the normal display of the indoor environment; The glass curtain wall LED film screen needs to meet 4000cd/㎡ in the daytime, which can ensure the normal display demand. If it is facing the sun, the brightness will be higher.

Glass curtain wall LED film display at night

If the brightness is not enough, the image does not look clear and cannot achieve good playback effect. But in the evening, if the LED film screen of glass curtain wall still maintains the brightness in the daytime, it is also not feasible, because such high brightness will cause serious light pollution, and will also affect traffic and pedestrians.

LianmanLED provides two solutions:

1. The brightness is adjusted by software. Generally, 256-level adjustment mode is adopted. Through the software operation interface, the PWM duty cycle driven by the LED film mounting screen is changed to realize the brightness change.

2. The simplest way is to automatically recognize the ambient light by installing a light sensor, automatically adjust the brightness through the function card, or reduce the brightness in the software.

The above is the solution to the problem that the background of the LED film screen is too bright. If you still have questions, you can contact your technical manufacturer for technical guidance and troubleshooting.
