Abstract: A display method and a terminal device are provided, so as to resolve a prior-art problem that CPU power consumption of the terminal device is relatively high because a display system of the terminal device processes three procedures in parallel in a Vsync period. The method is: determining, by the display system of the terminal device, a start moment of a first procedure in an (M+1) th Vsync period according to first processing duration of the first procedure in an M th Vsync period, so that the display system starts to execute a device display procedure before starting to execute the first procedure, the display system delays executing the first procedure in the (M+1) th Vsync period, so that a time required for processing three procedures in parallel in the (M+1) th Vsync period by the display system is reduced, and CPU power consumption of the terminal device is reduced.

Abstract: An electrophoretic medium comprises a plurality of particles suspended in a suspending fluid, the particles being capable of moving through the fluid upon application of an electric field to the medium, the fluid having dissolved or dispersed therein a polymer having a number average molecular weight in excess of about 20,000, the polymer being essentially non-absorbing on the particles. The polymer improves the bistability of the display (i.e., the period for which a written image persist without the display being refreshed) but does not greatly increase the viscosity of the suspending fluid, thus keeping the switching time of the display within reasonable limits. The medium may be encapsulated, or may be in the form a polymer-dispersed electrophoretic medium.

Abstract: An in-cell touch display device (100). A panel (110) has a plurality of data lines (DL), a plurality of gate lines (GL) and a plurality of touch electrodes disposed thereon. A touch driving signal (TDS) is applied to the plurality of touch electrodes when a driving mode is a touch mode. A data driver (120) drives the plurality of data lines (DL). A gate driver (130) drives the plurality of gate lines (GL). The gate driver (130) sequentially outputs a scanning signal for driving the plurality of gate lines (GL) to the plurality of gate lines (GL) when the driving mode is a display mode, and outputs a load-free driving signal (LFDS_gate) corresponding to the touch driving signal (TDS) to at least one gate line (GL) when the driving mode is the touch mode. A level shifter (810) generates the load-free driving signal (LFDS_gate). A multiplexer (820) inputs a scanning voltage (VGH/VGL) or the load-free driving signal (LFDS_gate) to the gate driver (130) depending on the driving mode.
