Abstract
The present application provides a touch display panel, a method for producing the same and a display apparatus. The touch display panel includes a liquid crystal screen and a protection cover plate covered at a light exiting side of the liquid crystal screen. The touch display panel further includes a sound elimination membrane, located at the light exiting side of the liquid crystal screen, and configured to eliminate sound waves generated when the touch display panel is touched. With the provision of the sound elimination membrane, the touch display panel can eliminate the vibration sound waves generated during the knocking touch process, and avoid the alignment difference of the liquid crystal molecules by the vibration sound waves, thereby avoiding a display mura caused by the vibration sound waves and further significantly suppressing the display mura generated during the knocking touch process.
