Abstract
The embodiments of the present invention disclose a method, a device and a system of touch panel display control. The method of touch panel display control comprises: acquiring the changes of the capacitances at respective positions of coupling capacitors, and determining pressed pixel units; determining the pressure on the pressed pixel units according to a first corresponding relationship between the changes and the pressure; and according to a second corresponding relationship between the pressure and a current gray level and a compensation signal, outputting a compensation signal corresponding to the pressure on the pressed pixel units, and the compensation signal is used for keeping the consistency of the light transmittance of the pressed pixel units with that of non-pressed pixel units. The method of the present invention keeps a consistent light transmittance between the liquid crystal molecules of the pressed pixel units and the liquid crystal molecules of the non-pressed pixel units, so that the image display of the overall touch panel keeps consistent, and the quality of the image displayed by the touch panel is improved.
