- the motion gesture sensing module maintains a reading mode according to the intensity of light received in a structure in which light is emitted from at least one light source and at least one light detector receives light reflected from a subject, thereby driving the screen. This can be done continuously. This is because when the user watches the screen of the display device, the distance between the device (more precisely, the motion gesture sensing module) and the user is close, so that the light detector may receive light having a relatively strong intensity.
- the motion gesture sensing module maintains the reading mode when there is no change in the relative movement of the subject in a structure in which the at least one light source emits light and the at least one photo detector receives the light reflected from the subject. It could make the drive run continuously. This is because sudden movement of the user does not occur when the user watches the screen of the display device.
