The invention provides a screen refreshing control method, which is applied to terminal equipment, the terminal equipment is configured with a display screen, and the method comprises the following steps: determining that the current refresh rate of the display screen is a first target refresh rate; determining that a display interface of the display screen comprises at least two application interfaces; determining a second target refresh rate according to the at least two application interfaces, and wherein the first target refresh rate is larger than the second target refresh rate; and refreshing the display screen according to the first target refresh rate and the second target refresh rate. Through the implementation mode, high and low refreshing applications can be considered at the same time, low frame rate applications are configured with low refresh rates, and high frame rate applications are configured with high refresh rates, so that the fluency of the applications can be ensured, the power consumption and heating of the mobile phone can be reduced, and better user experience is brought.

The invention discloses a drawing method for dynamically drawing a curve with gradual change shadows on a mobile phone screen. The method comprises the steps of (1) parameter configuration, includingcache parameter configuration, color configuration, timer configuration and coordinate parameter configuration, wherein in all the configuration processes, cache parameter configuration, color configuration and timer configuration are performed at a time after system initialization, the operation amount of layer drawing is reduced, and coordinate configuration is performed in the layer drawing process; (2) data caching, including caching of data and update of reference points, wherein real-time data is cached and dynamically allocated into a memory, a current position is marked, and if the range of caching length of the dynamically allocated data is exceeded, caching is continued from a starting position, the screen is refreshed, and the reference points are updated; (3) dynamic refreshing, wherein screen timing refreshing is set, the set refreshing rate is kept consistent with the screen refreshing rate of an operating system; and (4) layer drawing, including data boundary processing,coordinate calculation, drawing parameter configuration and curve drawing and gradual changing.

The invention relates to a touch interaction system based on a solid-state laser radar, and the system comprises: a computer main body which is internally provided with a data processing program and an application program; a projector, wherein the projector is connected with the computer main body through a display interface and is used for projecting computer pictures; an imaging plant, wherein the imaging plane is arranged on the rear side of the projector, and the projector projects a computer picture onto the imaging plane; and a solid-state laser radar arranged on the imaging plane, wherein the solid-state laser radar emits a light film, and the solid-state laser radar is electrically connected with the computer main body. According to the invention, the solid-state laser radar is matched with the common projector and the computer main body to form the interaction system, the installation and maintenance are simple, the solid-state laser radar has no mechanical wear, the refresh rate is high, the service life is long, the angle resolution of the solid-state laser radar is high, the distance is long, and the solid-state laser radar is especially suitable for large-size touch interaction occasions.
