Types

Capacitive touch can be divided in 2 types:

Mutual capacitive touch:

• True multi-touch
• Higher sensitivity
• Better immune to noise
• All point addressable(APA) type sensor
• Fast response time
• Detect and compare the intersection point (drive & sense) capacitance change, output is an array of capacitance values for each X-Y intersection

Self capacitive touch:

• Only requires 1-layer ITO sensor structure
• Support 1-touch true touch positon & 2-touch gestures
• Lower power consumption
• Scan X-Y channel sensors sequentially, detect the point of maximum capacitance to ground




Structure

Capacitive touch panel modules structures are determined by

Common touch panel module structures:


cover lens + 1 sensor glass (GG/GF/PG)

cover lens + 2 sensor films (GFF)

Cover lens + sensors with ITO layers:
sensor structrue
We also provide low resistance metal-ITO mesh film instead of ITO film.


Cover lens with ITO sensor layer
(OGS-One Glass Solution)

Cover lens with ITO layer (OGS):

*Depends on touch IC & ITO pattern.
*1=Single touch + 2 points gesture, ≦5”;
*2=True 2 points touch, depends on IC & ITO pattern, ≦5”;
*5=True 5 points touch, ≦4.3”.
