Analysis: Driver dah a nih hnuah, a awmna tur a siam that chuan bull mit lai takah vertical touch a awm lo. Touch screen-a signal line-a contact tha lo emaw, circuit hawn loh emaw.
Remedy: re-a dinhmun siam\\hat; Touch screen connect leh emaw thlak emaw tur chuan breakpoint zawng rawh.
Fault 2: Deviation tih kha hmet la.
Phenomenon: A khawih loh chuan mouse arrow chu hmun khatah a awm reng thin. Touch a nih chuan mouse arrow chu touch point midpoint leh original stop point-ah a awm a.
Analysis: Resistive touch screen-a hnathawhna hmun \\ha tak tiduhdahtu thil dang (non-active touch) a awm a.
Enkawl dan: Compression resistance touch screen-a hnathawhna hmun \\ha takah chuan ram dang thil chu paih chhuak tur a ni.
Fault Pathumna: Touch No Response .
Phenomenon: Mouse arrow hi screen khawih a nih chuan a che lo va, position change a awm lo.
Analysis: He thil thleng chhan hi a hnuaia mi ang hian a tam hle a ni:
(1) Touch screen a chhiat tawh avangin .
(2) Touch screen control card a chhiat tawh avangin.
(3) Touch screen signal line a chhiat tawh avangin.
(4) Host computer-a serial port chu a hlawhchham ta.
(5) Computer operating system a chhiat tawh avangin.
(6) Touch screen driver installation dik lo a awm.
Pathumnaah chuan, resistance screen common fault leh elimination .
1. Resistive Screen Touch Mouse chu hmun tlemteah chauh a kal emaw, resistive touch screen a phal loh emaw
Hei hi a tlangpuiin drive hmasa ber nen a ni a, touch screen calibration procedure kha run la. Touch screen calibration program pawh hi display resolution thlak hnuah (start-program) kalpui a ngai bawk.
2. Mouse chu display sir paliah hmun khatah a lang fo thin a, a chhan chu resistive screen-a touch area (resistive screen chunglam chu hmun hnih-ah a then a ni: touch area leh non-touch area, leh non-touch area-a click-a a chhan chu a chhantu a ni lo) chu display case emaw cabinet case emaw a ni. Pressed, point pakhat khawih tawh nen a inang. Cabinet case chu touch area-ah press a nih chuan cabinet leh monitor screen inkar hlat zawng i tisang thei ang. Display case chu touch area-ah press a nih chuan display case-a screw awmte chu tihzauh i tum thei ang. A awm lo a nih chuan kan technical department ah zawhfiah theih a ni.
3. Mouse chu kut lam hawiin a kal a, chu chu touch screen control box leh touch screen-a inzawm pali-wire connector a ni.
4. Touch Screen connection a connect em tih enfiah turin NO response. Host-a keyboard port-a connection pakhat (keyboard port aṭanga 5 volt touch screen working voltage la rawh) chu a connect lo. Khawngaihin connection kha check la, touch screen control box light en la, light on emaw off emaw a nih loh chuan control box a chhiat chuan. Khawngaihin thlak leh rawh. Confirmation a awm loh chuan touch screen driver kha la chhuakin computer kha restart la, driver chu reinstall leh la, a nih loh leh driver chu version thar zawk hmangin thlak leh rawh.
Device chu host-a serial port resource nen a inmil lo em tih chu hardware device tin check tur leh adjust tur a ni. Entirnan, NIC thenkhat install a nih hnuah default IRQ chu 3 a ni a, chu chu COM2 a IRQ nen a inmil lo. Chutiang a nih chuan NIC-a IRQ chu hman loh IRQ-ah thlak tur a ni. Computer motherboard leh touch screen control box te pawh a inmil lo pawh a ni thei. Host emaw motherboard emaw thlak leh tur a ni. Touch screen hi hun rei tak hman a nih a, touch screen hmun thenkhat chu khawih theih loh a nih chuan touch screen a chhiat vang pawh a ni thei, touch screen hi thlak leh rawh.
Palinaah chuan infrared touch screen common faults leh troubleshooting .
1. Double click hi a sensitive lutuk lo .
Infrared screen calibration program chu on la, a sensitivity siamrem la, sensitivity chu tihhniam rawh.
2. Eng dinhmunah nge drift ang tih hnuaiah .
Infrared screen hnathawh dan chu infrared rays hmanga hnathawh a nih avangin, sleeves leh a ang chi touch the infrared screen-a touch function pawh hman a nih avangin (entir nan, touch screen chu kut hmanga khawih a nih chuan sleeves pawh screen-ah a kal a, a hmel chu a lang ang.He harsatna hi finger point awmna hmunah a awm lo.
3. Eng dinhmunah nge touch screen hi calibrate a nih?
Infrared touch screen i install hmasak ber emaw, i computer resolution a inthlak chuan touch screen chu i recalibrate a ngai a ni. Calibration method chu hetiang hi a ni: "Calibration" tih kha click la. Calibration interface a rawn lan chuan interface a icon kha click la. Calibration a zawh chuan calibration interface chu a bo nghal vek ang. Calibration hnua data siam chu hman nghal a ni ang. Calibration a perform tha lo nia i hriat chuan pointer tracking a thawk tha hma chuan vawi tam tak calibrate theih a ni. Tichuan "Confirm" tih kha hmet la .
