hi i need display video on tft lcd i want use lpc1788 Is the 1788 gets the job done? What hardware do I need to get done? Please Help me, please Thanks
Video? Then you should consider a processor with video hardware - i.e. something that can perform processing of video data and not just have some ability to interface with a LCD panel.
Video means an ability to produce content and update lots of pixels on that display for every single frame displayed - and also that the frame rate is high enough. So hardware acceleration should not be ignored.
i want a film (some pictures) with high speed read on mmc(microsd)and display on tft lcd whit lpc1788 What is The maximum speed that I got Display the picture on TFTLCD whit 1788 ? I do not want the use to other processor all these things (read the image from memory and displayed on the LCD) I want to do 1788 thanks
So, without any idea of whether it is appropriate or even capable for this task, you're just going to stubbornly insist upon it?
Have you spent any time studying the documentation for this chip to determine its capabilities:

hi i previously study this documentation but i use emwin and lcd 7" But speed is displayed on the LCD is very low. Almost every second a Photo(bmp) And every 4 seconds a Photo(jpg) But I need more speed How can I do this faster (reading memory image and showing on the LCD side) do
If the time taken to show an image is too great then you need to consider ALL aspects.
When it is taking four times longer to show a jpg than a bmp then it is highly unlikely it's just the lcd interfacing that you need to consider. The processing required to decode a JPG is far greater than that of a BMP.
It looks like you're expecting too much from the processor.
"What is The maximum speed that I got Display the picture on TFTLCD whit 1788 ?"
Since there are not a large number of people who want to play video with the 1788 I think this is a task for you to find out. Please come back with the width * height * frame-rate that you can mange.
"I do not want the use to other processor all these things (read the image from memory and displayed on the LCD) I want to do 1788"
An important thing - there is a big difference between "I want" and "I can get". With the 1788 you will have to keep down frame-rate or resolution or both. And you will have to experiment to figure out how much processor budget to use for memory card transfers + decompression and how much to use for transfers to the LCD.
