Organic light emitting diode display device and manufacturing method thereof |
摘要 |
An organic light emitting diode display and a manufacturing method thereof are disclosed. The organic light emitting diode display includes: a flexible upper substrate; a first piezoelectric material layer and a second piezoelectric material layer formed inside the upper substrate; a pair of first electrodes brought into contact with the first piezoelectric material layer; a pair of second electrodes brought into contact with the second piezoelectric material layer; a flexible lower substrate disposed to face the upper substrate, and to have an organic light emission layer; and an opposed electrode disposed to protrude toward an inner side of the lower substrate and to face the pair of second electrodes, wherein a first sensor includes the first piezoelectric material layer and the pair of first electrodes, and a second sensor includes the second piezoelectric material layer, the pair of second electrodes, and the opposed electrode. |
