The product I’m using is “JHD161A” September 17, 2013 at 5:01 am #10459 AJISH ALFREDParticipant Hi Jasper, Just look at the screen, if you can see two rows of pixels then it is 16*2. Or just take a look at the back of the LCD, if you can see two large black colored ICs then it is 16*2, otherwise 16*1.
