9.34 OTP setting and programming
OTP (One Time Programming) is a method to adjust V
L6
. In order to eliminate the
variations of LCD module in term of contrast level, OTP can be used to achieve the best
contrast of every LCD modules.
OTP setting and programming should include two major steps of (1) Find the OTP offset and
(2) OTP programming as following,
Step 1. Find OTP offset
(1) Hardware Reset (sending an active low reset pulse to
RES pin)
(2) Send original initialization routines
(3) Set and display any test patterns
(4) Adjust the contrast value (0x81, 0x00~0x3F) until there is the best visual contrast
(5) OTP setting steps = Contrast value of the best visual contrast - Contrast value of original
initialization
Example 1:
Contrast value of original initialization = 0x20
Contrast value of the best original initialization = 0x24
OTP offset value = 0x24 - 0x20 = +4
OTP setting command should be (0x82, 0x04)
Example 2:
Contrast value of original initialization = 0x20
Contrast value of the best original initialization = 0x1B
OTP setting = 0x1B - 0x20 = -5
OTP setting command should be (0x82, 0x0B)
