1.The main differences between touchscreen and non-touchscreen liquid crystal displays lie in the interaction methods, technical structures, display quality and durability.
Interaction methods
Touchscreen liquid crystal displays (Touch Screen LCD displays):
By identifying the contact point position through sensors, it can be directly operated with fingers or styluses to achieve graphical interface interaction.
Non-touchscreen liquid crystal displays (No Touch Screen LCD displays):
Instructions need to be input relying on external devices such as mice and keyboards.
Technical structures
Touchscreen liquid crystal displays (Touch Screen LCD displays):
It identifies the contact position through sensors and can be directly operated with fingers or a stylus. A touch sensing layer (such as a resistive layer or a capacitive layer) is added to the liquid crystal panel, and additional processing of touch signals is required.
Non-touchscreen liquid crystal displays (No Touch Screen LCD displays):
It only contains display driver circuits and has a simpler structure.
Display quality
Touchscreen liquid crystal displays (Touch Screen LCD displays):
Due to the superposition of the sensing layer, it may affect the screen's light transmittance, color accuracy and response speed.
Non-touchscreen liquid crystal displays (No Touch Screen LCD displays):
It only contains display driver circuits and has a simpler structure. Focusing on display effects, more accurate color reproduction, suitable for professional image processing.
Durability
Touchscreen liquid crystal displays (Touch Screen LCD displays):
Maintenance cost is relatively high.
Non-touchscreen liquid crystal displays (No Touch Screen LCD displays):
More tightly packaged and stronger resistance to physical damage.
- 2.There are differences in the maintenance of touchscreen and non-touchscreen LCD displays, mainly reflected in the cleaning methods and daily usage habits:
Cleaning and maintenance
Non-touchscreen liquid crystal displays (No Touch Screen LCD displays):
Wipe the screen with a soft dry cloth or a dedicated cleaning cloth. Avoid using corrosive cleaning agents. If you need to clean stubborn stains, you can dip a small amount of neutral detergent and then wipe.
Touchscreen liquid crystal displays (Touch Screen LCD displays):
Direct contact with the screen surface should be avoided. It is recommended to use a lint-free cloth or a special cleaning cloth. Do not scratch with hard objects. For deep cleaning, you can dip a small amount of neutral detergent, but make sure it is completely dry before use.
Daily use
Non-touchscreen liquid crystal displays (No Touch Screen LCD displays):
Avoid displaying still images for long periods of time. It is recommended to set a screen saver or turn off the monitor at regular intervals.
Touchscreen liquid crystal displays (Touch Screen LCD displays):
Do not press the screen with your fingers or hard objects. Keep the touch gentle during operation. Avoid using it in an environment with strong electromagnetic interference, such as near the motor.
Environmental control
General maintenance:
Keep away from high-temperature, humid and strong magnetic field environments, and ensure good ventilation of the equipment.
Touchscreen liquid crystal displays (Touch Screen LCD displays):
Extra attention should be paid to the isolation of electromagnetic interference sources, such as keeping it away from high-frequency equipment.
Special maintenance
Non-touchscreen liquid crystal displays (No Touch Screen LCD displays):
Regularly check the connection status of the power cord and signal line to ensure they are stable and not loose.
Touchscreen liquid crystal displays (Touch Screen LCD displays):
The touch function needs to be calibrated regularly to avoid a decrease in sensitivity due to long-term use.
