7" or 8" TFT touchscreen

by Opporlando23 on Wed Oct 11, 2017 6:00 pm

Hello,

I have an inquiry regarding your products. I am looking for a 8" TFT Touchscreen display of a resolution of 800x400or better. I am using this screen to replace the factory screen in my cars navigation. The screen on the navigation now is a Toshiba Part #LTA080B170A. I can't find much on it. But what I have figured out is that the factory screen is an 8" TFT Touchscreen panel with resolution of 480X234 an a brightness of 400. Here is a link the screen https://ae01.alicdn.com/kf/HTB1_UKHOpXX ... -Ekran.jpg

I am looking for a screen replacement that will also send the touchscreen signal to the factory system it uses a standard 4 pin connection. As seen in this photo http://www.mp3car.com/filedata/fetch?id=2245612.

Here comes the cool part. I want to also hook up my phone to this screen and be able to mirror and control the phone from this touchscreen panel.

So the first thing is to find a driver that can take an HDMI input and display to the 8" TFT touchscreen. Then find a board that will split the 4 pin signal to either the factory system or the phone via usb. I do not know if this kind of splitter exists and if it will only send to one at a time or both. I need just one at a time.

The factory signal outputted to the factory screen is RGBS so I will also need the driver to take HDMI input and RGBS and output to the same screen and hopefully auto sense when the phone is connected or if not I can wire a manual switch. The driver would need to display the proper resolution for each input.

Lastly I would like to still manage the screen brightness with the factory system settings I believe this is achieved with the two backlight tubes. Here is a shot of the factory board mounted on the back of the screen. http://www.mp3car.com/filedata/fetch?id=2245614

So ultimately, I need an 8" TFT touchscreen, a driver for the screen that accepts RGBS and HDMI and a Touchscreen Driver that will be able to send the signal to either the phone or factory system.

Any help or input by anyone would be much appreciated. Thank You
