Hi,

Could any one help me how to configure FT5306 in NHD-5.0-800480TF-ATXL-CTP for query interrupt mode.

How to read pixel data from the display.

could anyone please suggest LED driver circuit for NHD-5.0-800480TF-ATXL-CTP display, currenly i am using FAN5333B IC for LED Back light driving circuit but when i connected display LED+ voltage drops from 28V to 15V so Display back light is not enabling. i have attached my circuit image.

Hi micheal,
 Thanks for the reply,
as per calculation frame buffer size is 1.15MB so i decided to go with external SDRAM interface using External Memory Controller(EMC) in Controller.
Is there any PCB guidelines for TFT data signals lines strip impedance in the PCB?? generally what could be the Impedance value for the Data line to interface with TFT display???

i am new to TFT display, i want to use NHD-5.0-800480TF-ATXL-CTP display in one of my application with LPC1788 controller. LPC1788 is an ARM Cortex-M3 based microcontroller, it has 512 KB flash, 64 KB SRAM and in built LCD controller with Selectable display resolution (up to 1024 X 768 pixels) and 24-bit true-color mode.
1. Are these specifications enough to handle the NHD-5.0-800480TF-ATXL-CTP display or not?
2. how to calculate Frame Buffer size for 24 bpp?
