**** BEGIN LOGGING AT Sat Feb 03 03:00:01 2018 Feb 03 11:56:47 Display technology is fascinating. For example, what's the difference between 4-wire resistive and 5-wire resistive? How to make resistive touchscreen more sensitive to the lightest touches, and why do people always say that capacitive is better in this regard? How many levels of pressure can resistive touch screen detect, and how to prevent it breaking down with time - is a screen protector sufficient or necessary? Feb 03 12:28:16 evtest_input /dev/input/event3 shows http://paste.debian.net/plain/1008644 Feb 03 12:29:38 so between 0 and 750 at least Feb 03 12:32:38 when two finger is touching, pressure value usually is lower then 50, for one finger is usually greater then 70 Feb 03 12:33:08 I use it for two finger recognition Feb 03 12:39:50 *than Feb 03 13:39:24 Wikiwide: we covered all this in a number of posts to neo900 thread. anyway here a few answers: 5wire is one cinductive plane and one resistive plane contacted in 4 corners. 4wire are 2 resistive planes contacted at upper lower and left right edge Feb 03 13:39:52 highly sensitive resistive TS uses oil separator instead of bumps Feb 03 13:40:54 capacitive works completely different and can sense close-aprox even. hard part in capacitive is to make it react on touches *only* Feb 03 13:41:46 R-TS can not really sense pressure, only area of touch. The idea is your finger tip goes more flat on stronger press and thus larger area Feb 03 13:43:31 "bearking down" or wearing may happen from separator bumps deforming, oil separator oxidizing and from deformation of foils and breaking of resistive contact layers Feb 03 13:43:59 treating screen carefully should gelp avoid most of that# Feb 03 13:45:03 help, even Feb 03 13:46:47 Wikiwide: see http://talk.maemo.org/showthread.php?p=1393889&highlight=4-wire#post1393889 **** ENDING LOGGING AT Sun Feb 04 03:00:01 2018
