Title: Display with embedded components and subpixel windows

Abstract:
A display may have an array of pixels. Each pixel may have a light-emitting diode such as an organic light-emitting diode. The organic light-emitting diodes may each have an anode that is coupled to a thin-film transistor pixel circuit for controlling the anode. Transparent windows may be formed in the display. The windows may be formed by replacing subpixels in some of the pixels with transparent windows. When subpixels are replaced by transparent windows, adjacent subpixels may be overdriven to compensate for lost light from the replaced subpixels. Adjacent subpixels may also be enlarged to help compensate for lost light. An array of electrical components such as an array of light sensors may be aligned with the transparent windows and may be used to measure light passing through the transparent windows.

Description:
BACKGROUND 
     This relates generally to electronic devices, and, more particularly, to electronic devices with displays. 
     Electronic devices often include displays. Displays such as organic light-emitting diode displays have pixels with light-emitting diodes. The light emitting diodes each have electrodes (i.e., an anode and a cathode). Emissive material is interposed between the electrodes. During operation, current passes through the emissive material between the electrodes, generating light. 
     The electrodes in an organic light-emitting diode display are formed from a photolithographically patterned layer of conductive material. Electrodes are organized in a regularly spaced array. This type of arrangement simplifies the layout of thin-film transistor circuits for the display. 
     It may be desirable to incorporate electrical components into a display. If care is not taken, the electrodes and other circuitry in a display may interfere with these components. 
     It would therefore be desirable to be able to provide improved display arrangements for accommodating the addition of electrical components. 
     SUMMARY 
     A display may have an array of pixels. Each pixel may have a light-emitting diode such as an organic light-emitting diode. The organic light-emitting diodes may each have an anode that is coupled to an associated pixel circuit. The pixel circuit may include thin-film transistor circuitry for controlling the anode. 
     Transparent windows may be formed by replacing subpixels in some of the pixels with transparent windows. When subpixels are replaced by transparent windows, adjacent subpixels may be overdriven to compensate for lost light from the replaced subpixels. Adjacent subpixels may also be enlarged to help compensate for lost light. 
     Further features will be more apparent from the accompanying drawings and the following detailed description.

     DETAILED DESCRIPTION 
     An illustrative electronic device of the type that may be provided with a display is shown in  FIG. 1 . As shown in  FIG. 1 , electronic device  10  may have control circuitry  16 . Control circuitry  16  may include storage and processing circuitry for supporting the operation of device  10 . The storage and processing circuitry may include storage such as hard disk drive storage, nonvolatile memory (e.g., flash memory or other electrically-programmable-read-only memory configured to form a solid state drive), volatile memory (e.g., static or dynamic random-access-memory), etc. Processing circuitry in control circuitry  16  may be used to control the operation of device  10 . The processing circuitry may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio chips, application specific integrated circuits, etc. 
     Input-output circuitry in device  10  such as input-output devices  12  may be used to allow data to be supplied to device  10  and to allow data to be provided from device  10  to external devices. Input-output devices  12  may include buttons, joysticks, scrolling wheels, touch pads, key pads, keyboards, microphones, speakers, tone generators, vibrators, cameras, sensors, light-emitting diodes and other status indicators, data ports, and other electrical components. A user can control the operation of device  10  by supplying commands through input-output devices  12  and may receive status information and other output from device  10  using the output resources of input-output devices  12 . 
     Input-output devices  12  may include one or more displays such as display  14 . Display  14  may be a touch screen display that includes a touch sensor for gathering touch input from a user or display  14  may be insensitive to touch. A touch sensor for display  14  may be based on an array of capacitive touch sensor electrodes, acoustic touch sensor structures, resistive touch components, force-based touch sensor structures, a light-based touch sensor, or other suitable touch sensor arrangements. 
     Control circuitry  16  may be used to run software on device  10  such as operating system code and applications. During operation of device  10 , the software running on control circuitry  16  may display images on display  14  using an array of pixels in display  14 . 
     Device  10  may be a tablet computer, laptop computer, a desktop computer, a display, a cellular telephone, a media player, a wristwatch device or other wearable electronic equipment, or other suitable electronic device. 
     Display  14  may be an organic light-emitting diode display or may be a display based on other types of display technology. Configurations in which display  14  is an organic light-emitting diode display are sometimes described herein as an example. This is, however, merely illustrative. Any suitable type of display may be used, if desired. 
     Display  14  may have a rectangular shape (i.e., display  14  may have a rectangular footprint and a rectangular peripheral edge that runs around the rectangular footprint) or may have other suitable shapes. Display  14  may be planar or may have a curved profile. 
     A top view of a portion of display  14  is shown in  FIG. 2 . As shown in  FIG. 2 , display  14  may have an array of pixels  22  formed on substrate  36 . Substrate  36  may be formed from glass, metal, plastic, ceramic, or other substrate materials. Pixels  22  may receive data signals over signal paths such as data lines D and may receive one or more control signals over control signal paths such as horizontal control lines G (sometimes referred to as gate lines, scan lines, emission control lines, etc.). There may be any suitable number of rows and columns of pixels  22  in display  14  (e.g., tens or more, hundreds or more, or thousands or more). Each pixel  22  may have a light-emitting diode  26  that emits light  24  under the control of a pixel circuit formed from thin-film transistor circuitry such as thin-film transistors  28  and thin-film capacitors). Thin-film transistors  28  may be polysilicon thin-film transistors, semiconducting-oxide thin-film transistors such as indium gallium zinc oxide transistors, or thin-film transistors formed from other semiconductors. Pixels  22  may contain light-emitting diodes of different colors (e.g., red, green, and blue diodes for red, green, and blue pixels, respectively) to provide display  14  with the ability to display color images. 
     Display driver circuitry may be used to control the operation of pixels  22 . The display driver circuitry may be formed from integrated circuits, thin-film transistor circuits, or other suitable circuitry. Display driver circuitry  30  of  FIG. 2  may contain communications circuitry for communicating with system control circuitry such as control circuitry  16  of  FIG. 1  over path  32 . Path  32  may be formed from traces on a flexible printed circuit or other cable. During operation, the control circuitry (e.g., control circuitry  16  of  FIG. 1 ) may supply circuitry  30  with information on images to be displayed on display  14 . 
     To display the images on display pixels  22 , display driver circuitry  30  may supply image data to data lines D while issuing clock signals and other control signals to supporting display driver circuitry such as gate driver circuitry  34  over path  38 . If desired, circuitry  30  may also supply clock signals and other control signals to gate driver circuitry on an opposing edge of display  14 . 
     Gate driver circuitry  34  (sometimes referred to as horizontal control line control circuitry) may be implemented as part of an integrated circuit and/or may be implemented using thin-film transistor circuitry. Horizontal control lines G in display  14  may carry gate line signals (scan line signals), emission enable control signals, and other horizontal control signals for controlling the pixels of each row. There may be any suitable number of horizontal control signals per row of pixels  22  (e.g., one or more, two or more, three or more, four or more, etc.). 
     A cross-sectional side view of a portion of an illustrative organic light-emitting diode display that includes a light-emitting diode (diode  26 ) and thin-film transistor circuitry for an associated pixel circuit (pixel circuit  48 ) is shown in  FIG. 3 . As shown in  FIG. 3 , display  14  may include a substrate layer such as substrate layer  36 . Substrate  36  may be a planar layer or a non-planar layer and may be formed from plastic, glass, ceramic, sapphire, metal, or other suitable materials. The surface of substrate  36  may, if desired, be covered with one or more buffer layers (e.g., inorganic buffer layers such as layers of silicon oxide, silicon nitride, etc.). 
     Thin-film transistor circuitry for pixel circuit  48  may be formed on substrate  36 . The thin film transistor circuitry may include transistors, capacitors, and other thin-film structures. As shown in  FIG. 3 , a transistor such as thin-film transistor  28  may be formed from thin-film semiconductor layer  60 . Semiconductor layer  60  may be a polysilicon layer, a semiconducting-oxide layer such as a layer of indium gallium zinc oxide, or other semiconductor layer. Gate layer  56  may be a conductive layer such as a metal layer that is separated from semiconductor layer  60  by an intervening layer of dielectric such as dielectric  58  (e.g., an inorganic gate insulator layer such as a layer of silicon oxide). Dielectric  62  may also be used to separate semiconductor layer  60  from underlying structures such as shield layer  64  (e.g., a shield layer that helps shield the transistor formed from semiconductor layer  60  from charge in buffer layers on substrate  36 ). 
     Semiconductor layer  60  of transistor  28  may be contacted by source and drain terminals formed from source-drain metal layer  52 . Dielectric layer  54  (e.g., an inorganic dielectric layer) may separate gate metal layer  56  from source-drain metal layer  52 . Pixel circuit  48  (e.g., source-drain metal layer  52 ) may be shorted to anode  42  of light-emitting diode  26  using a metal via such as via  53  that passes through dielectric planarization layer  50 . Planarization layer  50  may be formed from an organic dielectric material such as a polymer. 
     Light-emitting diode  26  is formed from light-emitting diode layers  40  on the thin-film transistor layers of pixel circuit  48 . Each light-emitting diode has a lower electrode and an upper electrode. In a top emission display, the lower electrode may be formed from a reflective conductive material such as patterned metal to help reflect light that is produced by the light-emitting diode in the upwards direction out of the display. The upper electrode (sometimes referred to as the counter electrode) may be formed from a transparent or semi-transparent conductive layer (e.g., a thin layer of transparent or semitransparent metal and/or a layer of indium tin oxide or other transparent conductive material). This allows the upper electrode to transmit light outwards that has been produced by emissive material in the diode. In a bottom emission display, the lower electrode may be transparent (or semi-transparent) and the upper electrode may be reflective. 
     In configurations in which the anode is the lower electrode, layers such as a hole injection layer, hole transport layer, emissive material layer, and electron transport layer may be formed above the anode and below the upper electrode, which serves as the cathode for the diode. In inverted configurations in which the cathode is the lower electrode, layers such as an electron transport layer, emissive material layer, hole transport layer, and hole injection layer may be stacked on top of the cathode and may be covered with an upper layer that serves as the anode for the diode. Both electrodes may reflect light. 
     In general, display  14  may use a configuration in which the anode electrode is closer to the display substrate than the cathode electrode or a configuration in which the cathode electrode is closer to the display substrate than the anode electrode. In addition, both bottom emission and top emission arrangements may be used. Top emission display configurations in which the anode is located on the bottom and the cathode is located on the top are sometimes described herein as an example. This is, however, merely illustrative. Any suitable display arrangement may be used, if desired. 
     In the illustrative configuration of  FIG. 3 , display  14  has a top emission configuration and lower electrode  42  is an anode and upper electrode  46  is a cathode. Layers  40  include a patterned metal layer that forms anodes such as anode  42 . Anode  42  is formed within an opening in pixel definition layer  66 . Pixel definition layer  66  may be formed from a patterned photoimageable polymer. The photoimageable polymer may be formed from an opaque material and/or a layer of opaque material such as black masking layer  66 ′ may cover other material in layer  66  (e.g., opaque layer  66 ′ may cover a layer of semitransparent polyimide or other polymer). 
     In each light-emitting diode, organic emissive material  44  is interposed between a respective anode  42  and cathode  46 . Anodes  42  may be patterned from a layer of metal on a planarization layer in the thin-film transistor layers of pixel circuit  48  such as planarization layer  50 . Cathode  46  may be formed from a common conductive layer that is deposited on top of pixel definition layer  66 . Cathode  46  is transparent so that light  24  may exit light emitting diode  26  as current is flowing through emissive material  44  between anode  42  and cathode  46 . 
     Display  14  may have an array of pixels  22  of different colors to provide display  14  with the ability to display color images. As shown in  FIG. 4 , each pixel cell  22 P in display  14  may contain a red pixel  22 R, a green pixel  22 G, and a blue pixel  22 B (as an example). These pixels, which may sometimes be referred to as subpixels, may have rectangular emissive areas (e.g., rectangular anode shapes) and/or may have emissive areas of other suitable shapes. White pixels, yellow pixels, and pixels of other colors may also be included in display  14 , if desired. 
     It may be desirable to incorporate electrical components into display  14  and/or device  10 . As shown in  FIG. 5 , for example, electrical components  84  may be incorporated into device  10  under pixels  22 . Components  84  may be discrete components or may be formed as part of a common integrated circuit or other shared component. Components  84  may, as an example, be mounted on a substrate such as substrate  82 . Substrate  82  may be, for example, a printed circuit (e.g., a rigid printed circuit board formed from a rigid printed circuit board material such as fiberglass-filled epoxy or a flexible printed circuit formed from a flexible layer of polyimide or other sheet of polymer). Components  84  and/or substrate  82  may be integrated into the layers that make up display  14  and/or may be mounted in alignment with display  14 . 
     Electrical components  84  may be audio components (e.g., microphones, speakers, etc.), radio-frequency components, haptic components (e.g., piezoelectric structures, vibrators, etc.), may be capacitive touch sensor components or other touch sensor structures, may be temperature sensors, pressure sensors, magnetic sensors, or other sensors, or may be any other suitable type of electrical component. With one suitable arrangement, which may sometimes be described herein as an example, electrical components  84  may be light-based components (e.g., components that emit and/or detect visible light, infrared light, and/or ultraviolet light). 
     Light-based components  84  may emit and/or detect light that passes through transparent windows  76  in display  14 . Windows  76  may be formed by selectively removing subpixels from a subset of pixels  22  in the array of pixels forming display  14 . Examples of light-based components  84  that emit light include light-emitting diodes (e.g., organic light-emitting diodes, discrete crystalline light-emitting diode dies, etc.), lasers, and lamps. Examples of light-based components that detect light include light detectors such as photodiodes and phototransistors. Some components may, if desired, include both light emitters and detectors. For example, components  84  may emit infrared light and may include light detector structures for detecting a portion of the emitted light that has reflected from nearby objects such as object  86 . Components of this type may be used to implement a proximity detector, a light-based fingerprint sensor (e.g., when object  86  is the finger of a user), or other light-based sensor. If desired, light-based sensors such as these may be implemented by illuminating object  86  with light  24  from one or more of pixels  22  and/or light  78  from one or more supplemental light sources such as discrete light-emitting diodes  80 , while using light-detecting components  84  to gather reflected light from object  86 . 
     Control circuitry  16  may be used in controlling the emission of light from light sources such as pixels  22 , components  84 , and/or light sources  80  and may be used in processing corresponding detected light from components  84  (e.g., to generate a proximity sensor signal based on light reflected from object  86 , to generate a fingerprint reading based on light reflected from object  86 , to process a captured digital image of a far-field object, that is captured using components  84 , etc.). 
     Components  84  and windows  76  may be interspersed with pixels  22  using any suitable arrangement. With one illustrative configuration, windows  76  and components  84  are arranged in an array that has a larger pitch than the array of pixels  22  in display  14 . There may be, for example, one window  76  and one corresponding component  84  for each set of 10-1000 pixels  22 , for each set of 100-10,000 pixels, for each set of more than 500 pixels, or for each set of less than 5000 pixels (as examples). In configurations such as these, pixels  22  are arranged on display  14  with a finer pitch than windows  76  and components  84 . Pixels  22  may, for example, be organized in an array having rows and columns and windows  76  and components  84  may be arranged in an array having a smaller number of rows and columns (e.g., in a rectangular patch that consumes less than 20%, less than 10%, less than 5%, more than 1%, or other suitable amount of the total area of display  14 ). Configurations in which windows  76  and components  84  are arranged in patterns other than rectangular arrays may also be used. Arrangements in which windows  76  and components  84  are arranged in rows and columns may sometimes be described herein as an example. 
     The pixels of display  14  may include red, green, and blue subpixels or subpixels of other colors. To create an array of windows  76 , some of the subpixels in an array of pixels may be selectively replaced with window structures. The human eye is less sensitive to blue and red light than green light, so with one suitable arrangement blue subpixels and/or red subpixels can be selectively replaced with windows  76 . Surrounding subpixels can then be overdriven to produce light that compensates for the loss of light from the replaced subpixels. If desired, the subpixel of a pixel adjacent to a window can be enlarged to help compensate for the loss of light. 
       FIGS. 6, 7, and 8  show how subpixels can be selectively replaced with windows. Pixel  22  of  FIG. 6  contains all of its subpixels: red subpixel R, green subpixel G, and blue subpixel B. Illustrative pixel NB of  FIG. 7  includes red subpixel R and green subpixel G, but blue subpixel B has been replaced with light transmitting window  76 . Illustrative pixel NR of  FIG. 8  includes blue subpixel B and green subpixel G, but red subpixel R has been replaced with light transmitting window  76 . 
       FIGS. 9, 10, and 11  show illustrative pixel arrays in which some of the pixels have been configured to include windows. In the example of  FIG. 9 , pixels  22  contain red, green, and blue subpixels (see, e.g., pixel  22  of  FIG. 9 ), whereas pixels NB contain no blue subpixels but rather include windows  76 . Each row of pixels NB has the same horizontal position. In the illustrative configuration of  FIG. 10 , each row of pixels NB is staggered with respect to the next (i.e., the pixels NB in the second row of the array of pixels NB of  FIG. 10  has been horizontally offset with respect to the pixels NB in the first row of the array of pixels NB in  FIG. 10 ).  FIG. 11  shows how pixels NB and pixels NR may be interspersed with each other when forming an array of pixels containing windows  76 . 
     To help suppress visible artifacts on display  14 , the amount of blue light produced by one or more of the pixels  22  adjacent to each pixel NB and the amount of red light produced by one or more of the pixels  22  adjacent to each pixel NR may be increased when displaying images on display  14 . If desired, the size of the subpixels (i.e., the size of the anodes and overlapping emissive material) that are adjacent to the replaced subpixels may be increased to help compensate for the loss of light from the replaced subpixels. Consider, as an example, the arrangement of  FIG. 12 . In the  FIG. 12  example, subpixel NB has a red subpixel R and a green subpixel G. Blue subpixel B is not present in subpixel NB to make space available for window  76 . Because blue subpixel B is absent from subpixel NB, the size of adjacent blue subpixel B in adjacent pixel  22 ′ has been increased. The increase in size of subpixel B (and the additional current that is provided to subpixel B) in pixel  22 ′ during image display operations may compensate for the loss of blue light due to the missing blue subpixel in pixel NB. The enlarged subpixel of pixel  22 ′ may therefore help suppress visible artifacts due to the presence of window  76  in place of the blue subpixel. If desired, a red subpixel in a pixel adjacent to a missing red subpixel may be enlarged in the same way. Subpixels of other colors can also be enlarged and/or multiple adjacent subpixels can be enlarged. 
     The foregoing is merely illustrative and various modifications can be made to the described embodiments. The foregoing embodiments may be implemented individually or in any combination.
