Abstract

The invention relates to the technical field of display, and discloses an electroluminescent display panel and an electroluminescent display device. The electroluminescent display panel comprises a substrate, a cover plate, and an organic electroluminescent unit located between the substrate and the cover plate. The electroluminescent display panel also comprises a piezoelectric touch control unit which is located between the substrate and the cover plate and also located at a side, departing from the light outgoing side, of the organic electroluminescent unit. According to the electroluminescent display panel (OLED), the touch control unit cannot reduce the transmittance of display light because the touch control unit is located at a non-light-outgoing side of the organic electroluminescent unit. Therefore, the OLED is higher in light utilization rate, and is higher in brightness. In addition, the OLED has a touch induction function which is higher in sensitivity and better in stability because the OLED employs the piezoelectric touch control unit which is high in pressure sensitivity and is good in stability.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electroluminescence display panel and an electroluminescence display device. Background technique [0002] In recent years, touch technology has developed rapidly, and touch display devices are also widely used due to the advantages of easy use and portability; the existing touch technology can be mainly divided into resistive touch technology, capacitive touch technology, and capacitive touch technology. Touch technology and piezoelectric touch technology, among them, compared with resistive touch technology and capacitive touch technology, piezoelectric touch technology has the ability to support any object touch, free from electromagnetic interference, sensitive to pressure, With a series of advantages such as high stability, it is one of the new touch technologies that have attracted much attention. [0003] At present, OLED is highly valued in the field of display techn...
