Brown - Web page: https://patentgrep.com/patent/US12016231B2 ## CPC - H10K 59/353: {characterised by the geometrical arrangement of the RGB subpixels} - H10K 50/19: Tandem OLEDs - H10K 59/131: Interconnections, e.g. wiring lines or terminals - H10K 59/352: {the areas of the RGB subpixels being different} - H10K: ORGANIC ELECTRIC SOLID-STATE DEVICES ## Abstract 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. ## Claims ### Claim 1 A full-color organic light emitting diode (OLED) display panel comprising: a plurality of pixels, each pixel comprising a plurality of sub-pixels including: a red sub-pixel comprising a red emissive layer configured to emit red light, a green sub-pixel comprising a green emissive layer configured to emit green light, and a blue sub-pixel comprising a blue emissive layer configured to emit blue light, wherein each blue sub-pixel is shared among more than one pixel of the plurality of pixels; and a plurality of data lines to provide display data to sub-pixels in the plurality of pixels; wherein the display panel has an overall data line-to-pixel ratio of more than two data lines per pixel and fewer than three data lines per pixel and the display contains only three colors of sub-pixels; and wherein the display panel comprises a single scan line for each row of pixels in the display panel. ### Claim 2 (depends on 1) The display panel of claim 1, wherein each blue sub-pixel is shared among at least two pixels. ### Claim 3 (depends on 2) The display panel of claim 2, wherein each blue sub-pixel is shared among at least four pixels. ### Claim 4 (depends on 2) The display panel of claim 2, wherein the area of the blue sub-pixel is at least 1.5 times the area of the larger of the red sub-pixel and the green sub-pixel. ### Claim 5 (depends on 4) The display panel of claim 4, wherein the area of the blue sub-pixel is at least twice the area of the larger of the red sub-pixel and the green sub-pixel. ### Claim 6 (depends on 5) The display panel of claim 5, wherein the area of the blue sub-pixel is at least four times the area of the larger of the red sub-pixel and the green sub-pixel. ### Claim 7 (depends on 6) The display panel of claim 6, wherein the area of the blue sub-pixel is at least six times the area of the larger of the red sub-pixel and the green sub-pixel. ### Claim 8 (depends on 7) The display panel of claim 7, wherein the area of the blue sub-pixel is at least eight times the area of the larger of the red sub-pixel and the green sub-pixel. ### Claim 9 (depends on 1) 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. ### Claim 10 (depends on 1) The display panel of claim 1, wherein the blue sub-pixel has a stacked architecture. ### Claim 11 (depends on 10) The display panel of claim 10, wherein at least one of the red sub-pixel and the green sub-pixel has a stacked architecture. ### Claim 12 (depends on 1) The display panel of claim 1, wherein at least one of the red sub-pixel and the green sub-pixel has a stacked architecture. ### Claim 13 (depends on 1) The display panel of claim 1, wherein each pixel in the display panel is capable of rendering white. ### Claim 14 (depends on 1) The display panel of claim 1, wherein blue sub-pixels in the display panel are aligned in columns parallel to an edge of the display panel. ### Claim 15 (depends on 1) The display panel of claim 1, wherein blue sub-pixels in the display panel are staggered relative to a line parallel to an edge of the display panel. ### Claim 16 (depends on 1) 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. ### Claim 17 (depends on 1) 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. ### Claim 18 (depends on 1) 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. ### Claim 19 A consumer electronic device comprising: a full-color organic light emitting diode (OLED) display panel comprising: a plurality of pixels, each pixel comprising a plurality of sub-pixels including: a red sub-pixel comprising a red emissive layer configured to emit red light, a green sub-pixel comprising a green emissive layer configured to emit green light, and a blue sub-pixel comprising a blue emissive layer configured to emit blue light, wherein each blue sub-pixel is shared among more than one pixel of the plurality of pixels; and a plurality of data lines to provide display data to sub-pixels in the plurality of pixels; wherein the display panel has an overall data line-to-pixel ratio of more than two data lines per pixel and fewer than three data lines per pixel and the display contains only three colors of sub-pixels; and wherein the display panel comprises a single scan line for each row of pixels in the display panel. ### Claim 20 (depends on 1) The display panel of claim 1, wherein the total number of sub-pixels in the full-color OLED display panel is less than three times the number of pixels. ### Claim 21 (depends on 19) The consumer electronic device of claim 19, wherein the consumer product 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.
