Hi all, We will change our LCD supplier and we have to assure that the new LCD will have the same contrast and backlight bright when I just plug it on my circuit, without hardware or software modifications. Actually i would not like to change the PWM contrast circuit neither modify the software to increase or decrease the PWM period. The problem is that i don't have any documentation and don't know the nominal features of the LCD we use in the moment. All i know is its part number "BC-1602C-SDBA-J-B-A00" I didn't found any datasheet or specification for this Part Number, the few information it says to me is: A - Normal Temperature Type/6:00 S - LCD type: STN 1602 - 16 columns/2 rows B - COB Package But i'm almost sure that what really plays a role on the contrast and backlight bright is the following features: - LCD Driver Voltage - Drive Method (DUTY, BIAS) - Drive IC Do you know how can extract such information of the part number or another way to assure that the new LCD will have the sabe bright? Thanks in advance. |
