Embodiment Construction

[0045] Certain terms are used throughout this specification and subsequent claims to refer to particular elements. It should be understood by those skilled in the art that manufacturers may refer to the same element by different terms. This description and subsequent patent applications do not use the difference in name as the way to distinguish components, but the difference in function of the components as the basis for distinction. "Include" mentioned in the entire specification and subsequent claims is an open term, so it should be interpreted as "including but not limited to". Furthermore, in order to enable those skilled in the technical field of the present invention to further understand the present invention, several preferred embodiments of the present invention are listed below, together with the accompanying drawings, to describe the composition of the present invention in detail. It should be noted that the drawings are for illustration purposes only and are not ...

Abstract

The invention discloses an organic electroluminescent display device which comprises a lower substrate, an outer cover substrate, a pixel control element, a first organic light emitting unit and a second organic light emitting unit. The outer cover substrate is opposite to the lower substrate. The pixel control element is arranged between the lower substrate and the outer cover substrate. The first organic light emitting unit is arranged between the pixel control element and the outer cover substrate. The second organic light emitting unit is arranged between the pixel control element and the lower substrate. The pixel control element is electrically connected with the first organic light emitting unit and the second organic light emitting unit.

Description

technical field [0001] The present invention relates to an organic electroluminescence display device, in particular to an organic light-emitting unit arranged on the upper and lower sides of a pixel control element to match each other to improve luminous efficiency, chromaticity performance or double-sided display and light emission. Organic electroluminescence display device. Background technique [0002] Electroluminescent display device (electroluminescent display device) has always been regarded as a replacement for liquid crystal display device due to its characteristics such as no need for color filter (color filter), self-illumination (no backlight module required) and low power consumption. Be the best candidate for the mainstream of next-generation display technology. Among various electroluminescent display devices, an organic light emitting diode display device is a relatively mature technology at present. However, according to the current state of development ...
