Lagging reaction, dim image, bad touch...have you ever bothered by poor aftermarket iPhone LCD? Touch issues in iPhone 7 and above are widely reported. 
The touch screen to become unresponsive is because that Apple chose to divert the touch control IC from the logic board to LCD flex ribbon cable in those models. When it comes to aftermarket screen, the design alteration is the main reason to cause touch issues in iPhone 7 and later models. Additionally, touch issue can be caused by bad materials, thicker structure and unstable voltage. 

The solution – voltage regulator IC 
Voltage regulator IC is the singular LCD performance protector used to provide a steady voltage for LCD screen. 

What is a voltage regulator IC for LCD? 

The voltage regulator IC generates a fixed output voltage of a preset magnitude that remains constant and stable regardless of changes to the LCD input voltage, current or load conditions, assuring the ultimate performance of the LCD.

  
How does it work? 

The voltage source in LCD circuit may have fluctuations and would not give the fixed voltage output, causing poor picture, dull touch and unstable LCD.While the voltage regulator IC maintains the output voltage at a constant value. Such improvement results in great reliability, stabilizes the voltage as well as secures the speed of its response.
