I’m getting more and more interested in screens that fail/decay. On line 8 today, I noticed the passenger information screens were not giving information about the anticipated arrival of the next train. Later that day, Wenhao kindly drove me and Wu Dan around downtown. As we went up Huaihai Road, which is the Oxford Street of Shanghai, we saw there were pairs of screens all the way up the road. Mostly they were carrying ads. But I also noticed that pixels were already failing, either because the colour was going wrong, or because they were dying and going black. With older screens, you can clearly make out how they are divided into squares of pixels. I would like to find out more about the technology, how difficult it is to repair, and why it decays so quickly. Somehow, that which signifies high tech wonder becomes tawdry very quickly.
