Abstract: A method for adjusting a touch screen, a touch chip, and an electronic terminal are provided. The method for adjusting a touch screen includes: receiving a characteristic signal corresponding to a usage scenario type of a terminal device that includes the touch screen; acquiring a touch screen adjustment parameter corresponding to the characteristic signal, where the touch screen adjustment parameter includes: at least one of a chip simulation parameter for controlling a touch chip of the touch screen and a firmware algorithm parameter; and adjusting an operating state of the touch screen based on the touch screen adjustment parameter. Through the embodiments of the present disclosure, a user can get excellent experience when using the touch screen in various usage scenarios.

Abstract: A method and apparatus for positioning a finger on a touch panel in a wet state and a touch detection apparatus are provided. The method includes: searching out suspect wet regions on the touch panel in a spacing coding manner, and determining a wet region from the suspect wet regions in a self-capacitive coding manner; traversing detection channels in the self-capacitive coding manner, and judging whether the detection channels satisfy a first condition; and if the detection channels in the wet region satisfy the first condition, determining a relative position relationship between a touch position of a finger and the wet region according to variations of feature data differences of the detection channels on the entire touch panel; or determining a relative position relationship between a touch position of a finger and the wet region according to variations of feature data differences of the detection channels outside the wet region.
