Nirmal Kumar just like @arbaman is already saying, you have humidity that is affecting your diffuser sheets. High humidity and heat from the LED's are cooking your sheets and causing the lines to show up and what you feel is the crinkling of the sheet from this. You could possibly disassemble the actual display panel and dry out/replace the diffuser sheets.
