Abstract

The invention relates to a measurement apparatus and a measurement method of mobile phone touch screen delay. The measurement apparatus comprises a mobile phone, a lower computer, a capacitance pen and an accelerometer. The mobile phone and the lower computer are connected by a wired connector, and the accelerometer is fixed to the capacitance pen. The mobile phone is used for providing an upper computer program and displayed delay measurement information. The capacitance pen is used for touching a screen of the mobile phone. The accelerometer is used for detecting the acceleration in the case of a touch action of the capacitance pen and generating corresponding output. The lower computer is used for collecting output data of the accelerometer and sending information to the mobile phone according to the size of the data. In the delay measurement method, the whole measurement process is divided into three steps according to the execution sequence: rough synchronization, fine synchronization and measurement. The error of rough synchronization is at a millisecond level; in the fine synchronization, an optimal delay error manner is found by multiple times of iterative approximation, and the delay error is reduced to a microsecond level; and in the delay measurement step, the touch screen delay is measured, and a final measurement result is displayed by the upper computer. By adoption of the measurement apparatus and the measurement method provided by the invention, the measurement precision of the reaction delay of the mobile phone touch screen can be effectively improved and reaches the microsecond level.

Description

technical field [0001] The invention relates to a delay measurement device and method, in particular to a mobile phone touch screen delay measurement device and measurement method. Background technique [0002] Currently, mobile phones are the most used products in the consumer electronics market. Applications such as audio-visual and games based on touch-screen mobile phones are widely used in daily life. However, the delay problem of the touch screen seriously affects the experience of using the mobile phone, especially for many mobile game applications that are sensitive to the response time of the touch screen. [0003] Usually without the use of peripherals, if you want to measure the delay of the touch screen of the mobile phone, you need to use a high-definition camera to shoot the action of touching the LCD display screen of the mobile phone, and calculate it by identifying and counting the number of frames between the touch action and the screen response. Touch sc...
