Problems solved by technology

When color filters are used to separate white light into three primary colors of red, blue, and green, the red and green spectrums are usually wider and the color purity is lower, and the color gamut performance of the panel is difficult to break through NTSC (National Television System Committee) 100%
At the same time, when white light is separated into red and green spectra, only a small portion of red or green light in the white light spectrum can be used
The energy loss of blue light and yellow light is relatively large
Due to the low energy utilization rate, it directly causes high power consumption when the panel is working

Abstract

The invention provides a white organic light emitting display which comprises a white organic light emitting display module, a quantum dot layer and a color filter layer. The white organic light emitting display module comprises white organic light emitting pixels; the quantum dot layer comprises red quantum dot parts, green quantum dot parts and blank parts arranged in multiple arrays; the colorfilter layer comprises red, green and blue filtering parts arranged in multiple arrays; and each red, each green and each blue filtering part correspond to one red quantum dot part, one green quantumdot part and the blank part respectively.

Description

[0001] 【Technical field】 [0002] The disclosure relates to the field of display technology, in particular to a white light organic light emitting display. [0003] 【Background technique】 [0004] The white organic light emitting diode (White Organic Light Emitting Diode, WOLED) technology is mainly used in the large-size display panel. WOLED technology is different from RGB three-color OLED technology widely used in small sizes. The biggest advantage is that the metal mask (Fine Metal Mask, FMM) in the manufacturing process does not need to be so fine, which can greatly reduce equipment costs. [0005] Currently, WOLED mainly utilizes a blue / yellow two-stack structure or a blue / red / green three-stack structure to realize white light. When color filters are used to separate white light into three primary colors of red, blue, and green, the red and green spectrums are usually wider and the color purity is lower, and it is difficult for the panel color gamut performance to break ...
