Abstract
The invention relates to a touch terminal and a display method thereof. The display method comprises the steps of adding one signal conversion module into the touch terminal; sending OPS video signals output by an OPS module and main-board video signals output by a television module directly to the signal conversion module; decoding and coding the received two paths of video signals respectively by the signal conversion module so as to correspondingly generate two paths of video signals in preset formats; and sending one path of the video signals of the two paths of the video signals in the preset formats to a displayer according to a channel control signal from the television module. As the signal conversion module only decodes and codes the OPS video signals output by the OPS module, but does not carry out any relevant processing such as picture quality processing and MEMC processing, display delay caused by the picture quality processing and the MEMC processing is avoided, and the touch response time of an OPS channel mode is further improved.
