A Method of Strike Position and Energy Measurement Based on Energy Distribution Vector Ratio

Abstract

The present invention is a method for measuring touching position, touching energy and display device thereof. While touching position is measured, at least two sensors are installed in dispersing form under the sensing panel of touch control equipment. The sensing panel is divided into a plurality of grids. The unit energy distribution vector of the touching signal is compared with the unit energy distribution vector of the benchmark signal of each grid, therefore touching position is obtained. While touching energy is measured, at least one sensor is installed under the sensing panel. The sensing panel is divided into a plurality of grids. Touching position would be obtained by the above method for measuring touching position or other methods. The touching energy could be calculated by comparing the detected touching signal energy with energy of benchmark signal at touching position in corresponding grid. The present invention could reduce the cost, complexity and power consumption of touch control equipment dramatically.

Description

technical field [0001] The invention relates to a method for measuring a touch position and a touch energy, in particular to a method for measuring a touch position and energy based on an energy distribution vector ratio for a touch device. Background technique [0002] Because of its simple and fast operation, touch devices have become the preferred configuration of current human-computer interaction electronic products. They can be seen everywhere from industry to home, from office to entertainment. While pursuing accuracy, stability, and convenience, people put forward more expectations and requirements, such as further enhancing sensitivity, reducing size, and reducing energy consumption. [0003] Taking electronic products with touch screens as an example, most mainstream technologies on the market currently use capacitive touch screens. However, the capacitive touch screen cannot directly sense the strength of the touch, and can only sense the click of the skin, but c...

Problems solved by technology

However, the capacitive touch screen cannot directly sense the strength of the touch, and can only sense the click of the skin, but cannot sense the click of fingernails, gloved fingers or other objects, so the operation is still inconvenient

At present, the above problems are mainly solved by the sensor group distributed under the touch screen, but it has several major disadvantages: 1. The sensor can only sense the force near it, so it is necessary to set up more sensors to form a group to cover the entire touch screen, so that It will increase the weight, complexity and power consumption of the device; 2. There are several layers of glass between the sensor and the finger touch. The energy of the finger touch can only be sensed by the sensor after being dispersed and attenuated by the glass, so the accuracy is not high. Difficult to accurately give the strength of the impact
