Organic electroluminescent devices
Devices, pixel arrangements, and fabrication techniques thereof are provided for devices that include pixels having red, green, and blue sub-pixels, where the blue sub-pixel is shared among more than one pixel in the arrangement. The display includes fewer than three data lines per pixel and uses only three colors of sub-pixel.

7 . The display panel of claim 1 , wherein the distance from one blue sub-pixel to the next blue sub-pixel is greater than the total distance across the each pixel, measured across the panel and parallel either to a scan line or a data line of the display panel.
8 . The display panel of claim 1 , wherein the blue sub-pixel has a stacked architecture.
9 . The display panel of claim 1 , wherein at least one of the red sub-pixel and the green sub-pixel has a stacked architecture.
10 . The display panel of claim 1 , wherein each pixel in the display panel is capable of rendering white.
11 . The display panel of claim 1 , further comprising one or more color altering layers.
12 . The display panel of claim 1 , wherein the display panel does not include one or more color altering layers.
13 . The display panel of claim 1 , further comprising power lines for blue sub-pixels in the display that are separate from power lines for other colors of sub-pixels in the display.
14 . The display panel of claim 1 , wherein at least some sub-pixels in the display panel comprise a stacked architecture, the display panel further comprising power lines for the stacked sub-pixels in the display that are separate from power lines for sub-pixels in the display having single junction emissive layers.
15 . The display panel of claim 1 , wherein the display panel is fabricated using a technique that requires no more than three depositions of different colors of emissive materials.
16 . The display panel of claim 1 , wherein edges of blue sub-pixels in the plurality of P pixels are arranged at varying distances from an edge of the display panel or a line parallel to an edge of the display panel.
17 . The display panel of claim 1 , wherein at least one of the red sub-pixel, the green sub-pixel, and the blue sub-pixel comprises an emissive layer comprising a phosphorescent emissive material, a fluorescent emissive material, or a combination thereof.
18 . A consumer electronic device comprising the display panel of claim 1 , wherein the consumer electronic device is selected from the group consisting of a flat panel display, a curved display, a computer monitor, a medical monitor, a television, a billboard, a light for interior or exterior illumination and/or signaling, a heads-up display, a fully or partially transparent display, a flexible display, a rollable display, a foldable display, a stretchable display, a laser printer, a telephone, a cell phone, tablet, a phablet, a personal digital assistant (PDA), a wearable device, a laptop computer, a digital camera, a camcorder, a viewfinder, a micro-display that is less than 2 inches diagonal, a 3-D display, a virtual reality or augmented reality display, a vehicle, a video walls comprising multiple displays tiled together, a theater or stadium screen, a light therapy device, and a sign.
19 . A full-color organic light emitting diode (OLED) display panel comprising:
a plurality of P pixels, each pixel comprising a plurality of sub-pixels including:
