Right now the standard size for e-reader screens is six inches, about the same size as a printed book. Although Prime View also has 8.1-inch and 4096-hue color screens ready for the market, and there is also the recently introduced 9.7-inch Kindle DX from Amazon, Liu feels that until foldable or rollable products hit the market, six inches will be "the outer limit."
目前電子書閱讀器螢幕的標準尺寸是 6 吋，大小恰如一本書，雖然元太還有 8.1 吋的產品及 4,096 色的彩色電子書面板等著上市，加上亞馬遜也剛推出了 9.7 吋的 Kindle DX，但劉思誠認為，在可折疊的產品還沒有問市前，6 吋應該是電子書的「終極尺寸」。
