The optimum combination is to place the LED screen behind other on-set objects and then use a camera and lens combination with a shallow depth of field to ensure that the screen is never in sharp focus. This is easier for panels with a finer pixel-pitch (i.e. higher resolution), albeit this often raises the screen's cost and, in some situations, compromises the brightness and colour range available, as tiny LEDs are less competent.

 

To achieve this, a balance between resolution and LED capabilities must be discovered.

To avoid individual pixels or moiré becoming visible on camera, a balance between resolution and LED capabilities must be achieved, while yet providing sufficient brightness and colour saturation. These are especially critical if the screen will be used to display High Dynamic Range (HDR) video material for greater realism at any moment.

It's also crucial to strike the perfect balance between the screen's brightness and traditional illumination. LED screens are an emissive light source that can be used in a variety of situations, especially because they produce accurate on-set reflections and coloured light.

Screen brightness can be readily regulated, and rather than dampening the video content, this should be done by modifying controls on the LED screen processor itself.

Avoid leaking conventional lighting over the screen, as this will render dark regions of the image grey, lowering overall contrast and making the LED screen illusion less convincing.

It's also important to strike the perfect balance between the screen's brightness and ambient lighting. LED screens are an emissive light source that can be used in a variety of situations, particularly because they produce realistic on-set reflections and coloured light.

Screen brightness can be readily adjusted, and this should be done by modifying controls on the LED screen processor itself (rather than dimming the video content) to ensure that the entire bit depth of the video signal is still used to avoid banding and other artefacts. It is important to take care.
