Flexible display panel with touch sensor function |
摘要 |
Provided is a display panel that has a touch sensor function, that is thin, and that has high flexibility. A plurality of sub-pixel electrodes (46) arranged in matrix and a counter electrode (35) are opposed to each other, and a pair of flexible substrates (21, 31) are opposed to each other, with the sub-pixel electrodes (46) and the counter electrode (35) being interposed therebetween. A desired display is carried out by controlling respective potentials of the plurality of sub-pixel electrodes with respect to the counter electrode. A pressure-sensitive conductive resin (48) whose electric resistance varies with a compressive force applied thereto is provided between the pair of flexible substrates. A change in a distance between the pair of flexible substrates that occurs according to a pressure applied to one of the pair of flexible substrates is detected based on a value of an electric current flowing through the pressure-sensitive conductive resin. |

1. A flexible display panel with a touch sensor function, comprising a plurality of sub-pixel electrodes arranged in matrix, a counter electrode opposed to the plurality of sub-pixel electrodes, and a pair of flexible substrates opposed to each other with the plurality of sub-pixel electrodes and the counter electrode being interposed therebetween, wherein the display panel performs desired display by controlling respective potentials of the plurality of sub-pixel electrodes with respect to the counter electrode, wherein
a pressure-sensitive conductive resin whose electric resistance varies with a compressive force applied thereto is provided between the pair of flexible substrates, a change in a distance between the pair of flexible substrates that occurs according to a pressure applied to one of the pair of flexible substrates is detected based on a value of an electric current flowing through the pressure-sensitive conductive resin, the pressure-sensitive conductive resin is provided in a matrix form, and the pressure-sensitive conductive resin keeps the distance between the pair of flexible substrates at a predetermined value. |
