LCD.
*2 The LCD module has temperature compensation circuit.
*3 In consideration of display quality, it is recommended that frame frequency is set in the range
of 70‑80Hz. When you have to use higher frame and clock frequencies, confirm the LCD's performan
‑ce and quality prior to finalizing the frequency values:
Generally, as frame and clock frequencies become higher, current consumption will get bigger and
display quality will be degraded.
