DIY TV from an Old Laptop Screen with 3D Printed Enclosure


Video

In this post, I will show you how to convert an old laptop screen to a portable TV

To convert your old laptop screen to TV, first remove the bezel covering the LCD panel.


 After removing the bezel note down the model number of the LCD panel and then place an order for the compatible LCD controller board

Tips: While placing the order ask the vendor to connect all the connections or ask for the guide

Next, remove all the connection which are connected to the LCD panel 


 Now connect the controller board to the LCD panel and do simple test to check if everything is working fine

Note: While testing always connect to an input device like a laptop




After making sure everything is working fine, I designed the enclosure for the LCD panel in FreeCAD and printed it with my Ender 3 3D printer

Note: Since my printing area was smaller than the size of the LCD Panel I had to divide the enclosure into 4 section

Next, I connected 4 Ohm 3 Watt speakers to the LCD controller board. Since I could not find suitable JST connector I had to hardwire the speaker connection through the backside of the panel

Next, I assembled all the parts together and tested it.
