摘要： A touch display screen includes a display panel, a touch-sensing part, a biosensor and a controller. The touch-sensing part is disposed on a light emitting side of the display panel and has a touch-sensing surface. The touch-sensing part includes a light-emitting device and a light receiver. The light-emitting device is used to provide at least one positioning light and at least one high-energy light. The light receiver is used to detect a change of the positioning light on the touch-sensing surface in response to a touch action and determine the position on which the touch action occurs on the touch-sensing surface. The biosensor is used to determine whether a living body getting close to the touch-sensing surface. The controller is used to drive the light-emitting device to selectively provide the positioning light and/or the high-energy light to the touch-sensing surface according to the determinations of the biosensor.

摘要： A multi-screen splicing structure has a plurality of display devices. Each display device includes a display panel, a plurality of transceivers, a wireless communications module, and a control circuit. Each transceiver has a transmitting component and a receiving component. The control circuit is coupled to the display panel, the transceivers and the wireless communications module, and is used to turn on the wireless communications module when the control circuit determines that another display device is approaching based on a status of signals received by the receiving components of the transceivers to enable the wireless communications module performing wireless communications with a wireless communications module of another display device. The control circuit may also control an orientation of an image relative to the display panel according to the status of signals received by the receiving components of the transceivers of the display device.

摘要： A multi-screen splicing structure has a plurality of display devices. Each display device has a display panel, a sensing module, and a control circuit. When the sensing module of a display device senses the sensing module of another display device, the control circuit determines which side of the display panel is adjacent to the proximate display device according to the sensing states of a plurality of sensors of the sensing module. The control circuit controls a portion of pixels adjacent to the proximate display device to display a pattern.
