Touch control driving method, touch control driving apparatus and touch control display device
First Claim
1. A touch control driving method, comprising:
- inputting a touch control driving signal at a first scan frequency for touch control scan;
detecting a writing frequency of a Random Access Memory (RAM) and a duration for the writing frequency; and
reducing the first scan frequency to a second scan frequency when the writing frequency of the RAM is larger than or equal to a first threshold and the duration for the writing frequency is larger than or equal to a second threshold.

Abstract
The embodiments of the present disclosure provide a touch control driving method, a touch control driving apparatus and a touch control display device, capable of reducing power consumption of a touch screen. The method comprises: inputting a touch control driving signal at a first scan frequency for touch control scan; detecting a writing frequency of a Random Access Memory (RAM) and a duration for the writing frequency; and reducing the first scan frequency to a second scan frequency when the writing frequency of the RAM is larger than or equal to a first threshold and the duration for the writing frequency is larger than or equal to a second threshold. The method can be applied in a process of touch control driving.
