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?

Click 'Export Passport' to save your multi-touch precision score, spatial error RMS, and digitizer health index in a JSON hardware passport.

PROTOCOLO DE DIAGNÓSTICO

Como Executar Este Teste de Tela (01, 02, 03)

Preparação

Limpe a superfície do monitor, desative sensores de luz ambiente e defina a resolução e taxa de atualização nativas.

Execução

Entre no modo de tela cheia (F11) e use os controles para navegar pelos padrões de teste.

Avaliação

Observe anomalias de diferentes ângulos de visão em um ambiente escuro. Consulte nossos guias para interpretar os resultados.

ARQUITETURA DE HARDWARE

Comparativo de Tecnologias de Painel

IPS Profissional (In-Plane Switching)

Precisão de cores e ângulos de visão superiores. Usado em monitores de referência. Sujeito a leve brilho IPS no escuro.

IPS Gamer (Fast IPS / Nano IPS)

Altas taxas de atualização e tempos de resposta rápidos para jogos, porém contraste estático menor que o VA.

Painel VA (Alinhamento Vertical)

Excelentes pretos profundos e alto contraste (3000:1+). Comum em telas curvas. Pode apresentar black smearing em movimento rápido.

OLED (LED Orgânico) e QD-OLED

Pixels autoiluminados proporcionam preto puro, tempos de resposta quase instantâneos e contraste infinito. Sujeito a ABL.

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.
