DT028BTFT-TST

Hello, i read the DT028BTFT-TST datasheet but it's not so clear how the 6-6-6 RGB signals are mapped into the DB15-DB0 bus, 

Thank you in advance

Character LCDs

LCD background lightness

Hello

I wish to buy some 16x2 characters LCD displays like the 162J. I need the best readability by low light with backlight switched off, so the background have to be very clear (I mean closest to white).

For example most calculators LCD displays are very good with a light gray background. But many avalaible 16x2 displays have a green background which is too dark.

I'm a bit confused by all the 162x variants and by the LCD technologies (TN, HTN, FSTN). Which one will be the best for that purpose ?

Difference between DT028ATFT & DT028BTFT

Hello,

i have question about your DT028ATFT and DT028BTFT display. I ask about non touchpanel displays versions. Is there any migration note between those two display? If not what's the difference between those displays?

VCOM max current draw and LED- wiring of the display DT070BTFT-PTS1

This is my first time wiring a TFT display and I have some questions about the display DT070BTFT-PTS1 :

  • What is the maximum current draw from the display VCOM input supply ?
  • Should LED- (pins 31 and 32) be connected to GND ?
  • Should we provide external resistor to limit the current of the backlight LEDs ?
  • Is it OK if my PSU 9.6V is shared between AVDD supply and VL (= 'LED+' - 'LED-')

Thanks in advance,
