A method for detecting touch-point coordinates includes: scanning a plurality of signal points in sequence to generate a plurality of original data including a plurality of original touch point data; performing a grouping algorithm for the original touch point data to group the original touch point data into a plurality of group sets; and calculating a barycentric coordinate of each of the group sets and outputting the barycentric coordinate as a touch-point coordinate of each of the group sets.

A method for mitigating pooling mura on LCD apparatus and a LCD apparatus are provided. The method is adapted for a LCD apparatus having a plurality of pixels. The LCD apparatus is for displaying frames according to a received original display data, and each of at least a part of the pixels comprises two pixel electrodes to drive a plurality of liquid crystal molecules between the two pixel electrodes. The method comprises changing a corresponding portion of the original display data so as to rotate at least a part of the liquid crystal molecules between the two pixel electrodes of the pressed pixel toward a natural angle; and maintaining another corresponding portion of the original display data. The natural angle is a finally-presented tilt angle of the liquid crystal molecules between the corresponding two pixel electrodes having substantially no potential difference therebetween.

A touch device is disposed on a substrate having a plurality of scan lines. The touch device comprises a plurality of readout lines and a plurality of sensors. The readout lines and the scan lines are intersected with each other, and the sensors are electrically coupled to the corresponding scan lines and the corresponding readout lines respectively. A scan signal is introduced into the scan lines in sequence to control whether turning on the sensors, and the scan signal comprises at least one first turn-on pulse and a second turn-on pulse to simultaneously turn on at least two sensors which are electrically coupled to different scan lines.
