Amazon's follow-up Kindle Fire may use a smaller screen than originally planned. Part suppliers claimed late Thursday that Chungwa Picture Tubes and LG Display, both of whom already make Kindle Fire displays, were ramping up their production for Amazon 8.9-inch screens. The Digitimes sources didn't have a timeframe, although they left room open for an iPad-like 9.7-inch version or the 10.1-inch panel that others had rumored might come.
