    摘要: Video displayers are provided for detecting image freezing in a video displayer with a multi-layer panel including a front layer and a pixel layer emitting pixel light in emitting direction towards the front layer. Front layer and pixel layer are configured to let light through. Video displayers further include a light reflector arranged in the multi-layer panel between pixel layer and front layer to reflect the pixel light from pixel layer in reflection direction towards pixel layer; a light sensor arranged to receive the reflected pixel light at receiving location and sense light variations in received reflected pixel light; and a control unit to receive light variations sensed by light sensor and to detect image freezing depending on received sensed light variations. Methods and computer programs implementing such methods are also provided which are performable by proposed video displayers.
