Q: What is Touch Matrix Defusal?

Touch Matrix Defusal is an interactive diagnostic game that tests capacitive digitizer multi-touch contact tracking, spatial accuracy, and touch release latency under fast multi-finger input.

Q: How does multi-touch digitizer multiplexing work?

Touchscreen digitizers scan an ITO conductive grid to detect mutual capacitance shifts across multi-finger touch points, transmitting spatial coordinates via W3C PointerEvents.

Q: Why does touch contact spatial error occur?

Spatial error occurs when finger contact area non-linearity or charger EMI line noise distorts the digitizer's calculated centroid position.

Q: How many simultaneous touch points does Touch Matrix Defusal test?

The game tests up to 10 simultaneous touch contacts with active tracking IDs, pressure vectors, and touch boundary geometry.

Q: What causes touch release latency on mobile screens?

Display controller firmware debouncing, driver event queuing, and browser main-thread frame scheduling can delay pointerup event dispatch.

Q: How does screen refresh rate affect touch defusal scores?

Higher refresh rate displays (120Hz / 144Hz) update touch target visuals twice as fast as 60Hz screens, reducing visual reaction feedback delay.

Q: Does charger EMI noise interfere with touch matrix defusal?

Unshielded third-party AC power adapters can inject high-frequency electrical noise into the capacitive glass, producing ghost touches or line jitter.

Q: Is Touch Matrix Defusal optimized for tablets and mobile devices?

Yes, the test is built using W3C PointerEvents and HTML5 Canvas for sub-pixel accuracy across smartphones, tablets, and interactive touch displays.

Q: How do palm rejection algorithms impact multi-touch games?

Palm rejection filters large contact radii (e.g. resting palms), ensuring intentional finger taps register without false rejection.

Q: How can I export my Touch Matrix Defusal diagnostic score?

诊断协议与流程

如何进行屏幕测试 (01, 02, 03)

准备工作

清洁显示器表面灰尘，关闭环境光自动感应，并将屏幕设置为原生分辨率与最高刷新率。

开始执行

进入全屏模式 (F11)，利用诊断控制栏依次切换并观察各种专业测试图案。

结果评估

在暗室环境下从不同视角细致观察屏幕均匀度、坏点与拖影，参考工程指南判断面板品质。

OPTOMETRIC ERGONOMICS & NON-MEDICAL NOTICE

Display Test Online is an engineering calibration utility for electronic visual displays (LCD, OLED, QD-OLED, MicroLED) and mobile touch digitizers. This software is NOT a medical eye exam, optometric vision test, or diagnostic health utility.

To reduce Digital Eye Strain (DES) during display calibration, apply optometric ergonomics:

The 20-20-20 Rule: Every 20 minutes, look at an object at least 20 feet away for 20 seconds.
Ambient Illumination: Ensure room ambient lighting matches display brightness levels (~100–150 nits for standard SDR workloads).
Optimal Viewing Distance: Place your screen approximately 20 to 30 inches (50–75 cm) from your eyes.
