Abstract
A touch display panel and method for measuring touch points are provided. The coordinate of each of touch points located in a first sub-display region and a second sub-display region can be measured by a first touch chip and a second touch chip respectively. When it is necessary to use the coordinates of the touch points located in the second sub-display region for joint calculation for obtaining the coordinates of the touch points located in the first sub-display region, the data can all be obtained through the first touch chip. When it is necessary to use the coordinates of the touch points located in the first sub-display region for joint calculation for obtaining the coordinates of the touch points located in the second sub-display region, the data can all be obtained through the second touch chip, thereby ensuring the unity of data sources, and increasing data accuracy.
