Organic luminescent display with solar cell

Abstract

The invention discloses an organic luminescent display with a solar cell. The organic luminescent display comprises a substrate, at least one organic luminescent unit, and at least one solar cell unit. The organic solar unit is arranged on one side of the substrate and comprises a first electrode layer, an organic luminescent material layer, and a second electrode layer. The organic luminescent material layer is arranged between the first electrode layer and the second electrode layer. The first electrode layer is arranged between the organic luminescent material layer and the substrate. The solar cell unit is arranged on one side of the substrate and comprises a third electrode layer and an organic solar cell material layer. The organic solar cell material layer is arranged between the second electrode layer and the third electrode layer. The provided organic solar cell unit can provide a similar effect of a color light filter, can directly absorb the lights in the organic luminescent display and external lights, is capable of converting the light energy into electric energy, and improves the situation of energy loss.

Description

technical field [0001] The present invention relates to an organic light-emitting display (organic light-emitting display, OLED) with a solar cell, in particular to an organic light-emitting display with an organic solar cell (organic photovoltaic cell, OPV cell). Background technique [0002] An organic light-emitting display uses organic light-emitting materials on a matrix display panel, and achieves the effect of displaying different brightnesses by controlling the magnitude of the driving current. Because organic light-emitting displays have the advantages of power saving, no viewing angle limitation, low manufacturing cost, fast response speed, wide operating temperature range, and miniaturization and thinning along with hardware devices, they have great potential in flat-panel display systems. development potential. However, the luminous utilization efficiency of traditional OLEDs is still not high. The reasons include that most organic light-emitting materials have ...

Problems solved by technology

However, the luminous utilization efficiency of traditional organic light-emitting displays is still not high. The reasons include that most organic light-emitting materials have a relatively high refractive index, so the light generated is prone to total reflection and will not exit the organic light-emitting display, resulting in energy waste.

In addition, in order to prevent ambient light from entering the organic light-emitting display and being reflected by the metal electrodes therein and affecting the display effect, a circular polarizer must be attached to the surface of the traditional organic light-emitting display, resulting in an increase in thickness and cost
