![]() The table below shows some sample data which we used to locate the good and bad zones. After locating the line positions, we used the difference between the original lines and the red lines to calculate the average and maximum gap values. First, we collected the average gap values and then used our test instrument to draw six red lines on the screen. We used these gap values to analyze sensitive areas (good zones) and non-sensitive areas (bad zones). Generally speaking, smaller gaps between pixels is better. We tested touch screen quality along the six red lines and within the four zones shown in the figure below.įirst, we used data provided by touch testing apps to calculate the average gap and maximum gap. Anti-Interference to evaluate possible touch screen interference due to various wireless transmission (Wi-Fi/BT) and power charging conditions.User Behavior such as scroll, multi-touch, and drag.We divided our touch tests into two categories: To help the reader understand the test details, we have provided visual aids and summary tables below. These tests evaluated touch screen sensitivity, interference capability, scroll/drag performance, etc. To understand these factors, we present some recent testing that our smartphone validation team performed. ![]() In this article, we explore some important factors that contribute to smartphone touch screen quality. In the ultra-competitive smartphone market, delivering a quality user experience is the key to success. Although touch technology is not new, some touch screens still perform poorly. Most smartphones include touch interfaces so that users can use simple gestures, like dragging, scrolling, sliding, or swiping to interact with their phone.
