Abstract: A terminal device and a display method are provided. The terminal device includes a proximity sensor, a memory, a controller and a display screen. The proximity sensor is configured to sense a distance from a human eye to the display screen. The memory is configured to store contents to be displayed. The controller is configured to determine a target resolution for the contents to be displayed based on the distance sensed by the proximity sensor, adjust an original resolution of the contents to be displayed to the target resolution to generate target display contents having the target display resolution, and control the display screen to display the target display contents in full screen. The target resolution may be inversely proportional to the distance. Solutions provided conform to the viewing characteristics of the human eye, and so can improve the user experience, and reduce the power consumption of the display screen.

Abstract: The present application provides a terminal apparatus, which comprises a sensor, a controller, and a display screen. The sensor is used to sense a focused area and a non-focused area on the display screen when the human eye or an observing device views the display screen. The controller is used to display a display content within the focused area at a first display resolution and to display a display content within the non-focused area at a second display resolution, based on a sensing result of the sensor, wherein the first display resolution is higher than the second display resolution. The present application further provides a display method, which is used to display an image on the display screen of the terminal apparatus.

Abstract: A driving device and a liquid crystal display device are disclosed. In the driving device, a charging efficiency difference between a positive polarity voltage and a negative polarity voltage on a pixel can be compensated through increasing a duration of a gate driving signal, shortening a time period during which the positive polarity voltage is provided to a source line, and prolonging a time period during which the negative polarity voltage is provided to the source line. In this manner, the technical problem of non-uniform brightness of an image displayed in a traditional liquid crystal display panel and unsatisfactory display effect thereof can be solved.
