Black Spots on screen with colored lines


I have been using my Macbook Pro for about 2 years now, and I have maintained quite good care of it. Accidentally, I shut my computer lid on a pair of earphones.

When I opened it back again, I found out that there were two black spots where the earphones were and colored lines. To test this out, I rapidly changed the screen. The lines that were working changed colors appropriately but it's not working.

What I have tried is:

- Applying pressure on it with a piece of cloth

- Using software that has rapidly color-changing pixels.

The next morning, I found out that the lines have spread, and now my entire computer screen had either colored lines or black rectangles and spots.

Can anyone help me with this, or do I have to replace my computer screen?

Everything else works fine, but just this.

My OS X is El Capitan.

Ouch! Sorry guy it's time for a new screen (display assembly).

Basically, the black spots are caused by the displacement of the liquid that is sandwiched between the glass plates (liquid crystal). The lines are caused by the breaking of the very tiny wires plated on the inside surface of the glass that electrofies the given pixel cell row or column depending if the line is horizontal or vertical. In some cases the driver logic at the edge gets damaged which can also create blocks of cells to be offline. Nothing here is fixable by any actions you applied.
