CURSOR FOR LCD DISPLAYS |
摘要 |
YO9-91-051 CURSOR FOR LCD DISPLAYS A method displays a visual "trail" (12b) behind a moving cursor (12a) so that the cursor does not disappear from a liquid crystal display (12) during rapid cursor movement. The method interpolates and displays one or more intermediate cursor locations between a previous cursor location and a present cursor location. A method also extrapolates one or more future cursor locations (12c) from a present location and prematurely turns on, or biases, pixels located at the extrapolated future locations so that a significantly shorter period of time is required to cause the pixels to become visually distinct. The method also interpolates intermediate cursor locations between the present location and the one or more extrapolated locations and prematurely turns on the pixels at the interpolated locations.
