FPC is one of the core components of a touchscreen system, and its supply voltage has a significant impact on the overall performance of the touchscreen. The supply voltage for touchscreens typically ranges from 3.3V to 5V, with the specific value depending on the model and specifications of the touch control board.
When selecting the supply voltage, it is necessary to refer to the touchscreen specification sheet or technical manual to ensure that the selected voltage value meets the operational requirements of the touch control board.
Impact of Supply Voltage on Touchscreen Performance
Supply voltage directly affects touchscreen performance. Excessively high voltage may cause touchscreen damage or performance degradation, while excessively low voltage may prevent the touchscreen from functioning properly. Therefore, when selecting the supply voltage, it is essential to fully consider the touchscreen's actual requirements and operating environment.
Additionally, power supply stability is another important factor affecting touchscreen performance. Unstable supply voltages may cause irregular system crashes or screen distortion. Therefore, when designing the touchscreen power supply circuit, effective measures must be taken to ensure power supply stability.
