1. How can I clean the touchscreen?
You can periodically clean the glass touch screen surface using an isopropyl alcohol and water solution ratio of 50:50. You can also use straight isopropyl alcohol or any proprietary glass neutral cleaner. Apply the cleaner with a soft, lint free cloth. Always dampen the cloth and then clean the screen, be sure to spray the cleaner onto the cloth, not the screen.
2. How can I improve the touchscreen sensitivity?
If the touchscreen shows low sensitivity, you can adjust the sensitivity level in the touch driver control panel. Level Four is recommended.
3. How can I solve the drifting problem?
A drifting problem occurs when you touch the screen, the cursor does not move to the intended location. If the drifting of the cursor is regular, you can solve the problem by calibration; if the drifting of the cursor is irregular, there is probably interference around the touch system, and you can adjust the sensitivity level to a lower one.
4. What are the advantages of Surface Acoustic Wave touchscreen over other touchscreens?
Surface Acoustic Wave (SAW) touchscreen features a higher transmission, strong reliability, and works well even with scratches. Therefore it shows powerful EMC performance.
5. Will the dust affect the touch performance?
The dust in the viewing area of the display will not affect the touch performance. However, too many dusts accumulated around the reflection strips area will lead to the malfunction of the touchscreen. This generally happens to SAW touchscreen and can be solved by clearing the dusts. CJTouch offers SAW water-pro and dust-pro touchscreens.
6. Why the SAW touchscreen takes a longer response time?
This delay in response time may be caused by droplets on the screen surface. Please clean the touchscreen with a soft dry cloth.
7. How can I solve the LCD color distortion problem?
Step-1: To judge the color distortion is in partial area or in the whole display area. If the color distortion happens in the whole display area, please go into the OSD menu and “Auto Color” the touch monitor, and then the problem will be solved. If the problem is still there or if the color distortion is in partial area, please go to Step-2;
Step-2: Please change another VGA cable to see whether the problem is still there. If yes, please go to Step-3;
Step-3: Please change the A/D Board of the touch monitor to see whether the problem is still there. If yes, please go to Step-4;
Step-4: Please change the LVDS cable of the touch monitor to see whether the problem is still there. If yes, the problem should be from the LCD Panel.
Step-5: To change the LCD Panel.
8. How can I solve the failed Lamps problem?
Step-1: At first, we need to confirm the detailed phenomenon. Sometimes when there is a failed A/D board or LVDS cable, the LCD panel will have a dark lane which seems that there is a defective CCFL. So at first we need to confirm the root cause.
Step-2: Please change the A/D Board and the LVDS cable of the touch monitor to see whether the problem is still there. If yes, the problem should be from the LCD Panel.
Step-3: To change the LCD Panel.
9. How can I solve the problem of dead zone in partial area of the touchscreen?
If the dead zone is in the middle area of the touch screen, the problem is always caused by dust or stain accumulating on the edge of the touch screen or on the reflection stripes of the touch screen. For this kind of dead zone, the controller LED will not brighten when you touch in the dead zone. The solution is to disassemble off the front bezel to clean the touch screen and inside surface of the front bezel with alcohol and soft cloth. Please pay attention to the dust-proof stripes stuck onto the internal surface of the front bezel. Sometime when there is a defective dust-proof stripes, there would be some gummy deposit left onto the touch screen to lead the dead zone. For this kind of situation, to replace the defective dust-proof strips is necessary.
If the dead zone is on the edges and the controller LED will not brighten when you touch in the dead zone, the solution is the same as above.
If the dead zone is on the edges and the controller LED will brighten when you touch in the dead zone, the problem should come from the calibration. Please kindly go into the touch driver control panel to re-calibrate the touch screen.
10. Why the dust-pro touchmonitor sometimes can’t be touch-enabled?
This is probably due to the failure of the transducers, and they may be destroyed when you install the bezel. If the product is still within the warranty period, you can send it back to us for reparation.
