Ti umuna a tampok ti touchscreen: transparent, direkta nga apektaranna ti visual effect ti touch screen. Transparency has the℃of transparency issues, infrared technology touch screen and surface acoustic wave touch screen only separated by a layer of pure glass, transparent can be counted as the best, other touch screen this is to be well-elaborated, "Transparent", in the touch screen industry, is a very general concept, many touch screen is multilayer composite film, It is not enough to generalize its visual effect by just a little, it should include at least four Tampok: Kinalawag, pannakaballikug ti kolor, panagpanunot ken kinatadem, ken mabalin pay a mabingbingay, a kas ti reflective℃ti panaganinaag ken ti℃ti diffraction reflection, ngem ti reflection ti rabaw ti touch screen ket saan a nakadanon iti saklaw ti CD, para kadagiti agar-aramat,
Dagitoy uppat a metrics ket kangrunaanna nga umdas.
Ti maikadua a tampok ti touchscreen: ti touch screen ket maysa nga absoluto a sistema ti koordinado, tapno agpili no ania ti direkta a punto a, ken ti mouse daytoy a kita ti relatibo a sistema ti panagposision ti nasken a panagdumaduma ket ti intuitibo a naikabil. The absolute coordinate system is characterized by the location of each coordinate and the last location of the coordinates have no relationship, the touch screen is a set of independent coordinate positioning system, each touch of data through the calibration data to the screen coordinates, so that the touch screen this set of coordinates in any case, the same point of output data is stable, If not stable, then this touch screen can not guarantee the absolute coordinate positioning, point is not allowed, this is the most afraid of the touch screen problem: drift.
Iti teknikal, awan ti garantia a ti isu met laeng a sagiden tunggal maysa a datos ti isu met laeng a datos ti panagsample ti touch screen ket saan a maliklikan a mang-drift iti daytoy a parikut, adda ti drift phenomenon laeng a kapasitibo a touch screen.
Maikatlo a tampok ti touchscreen: ti panangrikna iti pannakasagid ken pannakaiposision, nadumaduma a teknolohia ti touch screen ti agpannuray kadagiti bukodda a sensor nga agtrabaho, ken uray ti sumagmamano a touch screen a mismo ket maysa a set ti sensor.
Ti bukod a prinsipio ti panagposision ken dagiti agsasaruno a sensor ket mangikeddeng ti kapartak ti sungbat, kinamapagtalkan, kinatalged ken biag ti touchscreen.
