Definitions

  • the invention relates to a circuit arrangement for arranged in a two-dimensional matrix organic light-emitting diodes.
  • Microdisplays ie very small displays with screen diagonals of less than or equal to 20 mm, offer the possibility of displaying image and video information in a high-resolution and user-specific manner, ie for one or more users only.
  • Areas of application of microdisplays are in the field of near-to-eye applications (applications with displays close to the Eye). These are, for example, video glasses that can be connected to mobile multimedia devices (smartphones or mobile audio and video players). These video glasses can be used for mobile TV, video presentation or presentation of Internet content.
  • microdisplays in digital photo and / or video cameras can be used as a high-resolution electronic viewfinder.
  • the microdisplay is mounted in a See Through optics (goggles). Through these glasses the user sees the real environment and via the microdisplay additional information in form of pictures, texts, graphics etc. can be superimposed on this image of the real environment. This can be used, for example, in the maintenance of complicated systems and machines for the display of assembly instructions or instructions. In aerospace engineering, pilots can display the display of various gauges. In medicine, the data of important devices can be additionally displayed for surgeons. In addition, versatile applications in the military field are conceivable.
  • microdisplays are picoprojectors, ie very small projectors which project image and video contents onto a flat surface and make them visible to several users.
  • Such projectors with microdisplays can also used in the measurement technique for the projection of defined patterns on a surface to be examined and the subsequent optical detection of the 3-D structure of this surface.
  • the light-modulating displays include LCOS (Liquid Crystal on Silicon) and MOEMS-based microdisplays. These technologies require additional external lighting that adds complexity, size, and weight to the overall system, while providing limited contrast (typically ⁇ 1: 100).
  • OLED organic light emitting diodes
  • Each organic light emitting diode as pixel is controlled by its own integrated electronic circuit.
  • This pixel circuit is designed so that it is writable with the image information in the form of an electrical voltage or a current.
  • the image information is stored in the circuit associated with the organic light emitting diode and this circuit drives the OLED with an electrical current or voltage corresponding to the stored image information.
  • microdisplays with organic light-emitting diodes for all these concepts is limited to low ( ⁇ 200 Cd / m 2 ) to medium brightness (up to 5000 Cd / m 2 ), ie to the fields of application with the information display for a single person and applications close to the Eye.
  • the field of application is limited by the maximum displayable brightness of such microdisplays. The brightness depends on the efficiency and voltage requirement of the organic light emitting diodes and the electrical current and voltage driving capability of the circuit.
  • microdisplays are used with organic light emitting diodes for projection applications and see-through applications with high maximum brightnesses ( ⁇ 10000 Cd / m 2 ) and are driven with a corresponding organic light emitting diode associated circuits.
  • OLED microdisplays The field of application of currently available OLED microdisplays is limited to unidirectional, image rendering microdisplays. After DE 10 2006 030 541 A1 is also an application in bidirectional microdisplays, ie microdisplays with image display functionality and image capture functionality or optical detection function feasible.
  • the object of the invention is to provide an alternative circuit arrangement for controlling arranged in a two-dimensional matrix organic light-emitting diodes as imaging elements, with which a substantial influence on the brightness of the electromagnetic radiation emitted by the organic light emitting diodes is possible.
  • each organic light-emitting diode by means of a memory circuit, a sense amplifier and a driver circuit is individually controlled.
  • the driver circuit is formed with at least three transistors connected in series and a further output transistor whose drain is connected to the anode of the respective organic light-emitting diode.
  • the drain of this transistor is connected to the source of the transistor connected in series below it and the two gates of the subsequently arranged in the series circuit transistors forming a switch to the output of the readout amplifier and applied to the electrical output voltage VsenseOut.
  • the electrical voltage V Drive is an adjustable analog, time-constant reference voltage. This voltage has a value that is between the LVDD and ground.
  • This reference voltage can be supplied directly from the entire circuit for the display with the organic light-emitting diodes or externally fed. It determines the maximum brightness of the electromagnetic radiation emitted by the organic light emitting diodes and can be set differently for each of the primary colors of the emitted light of the display.
  • the drains of the two transistors forming the switch are connected to the source of the output transistor whose gate is connected to ground potential or supplied with a negative electrical voltage.
  • the output transistor for each organic light emitting diode is disposed in a separate, electrically isolated well of a substrate. The connection of the well and the source of the output transistor are connected to each other.
  • the transistor whose source is connected to the transistor acting as a driver, should be a PMOS transistor and the transistor whose gate is connected to the gate of the second series-connected transistor and common to the output of the readout amplifier should be NMOS transistors ,
  • a further transistor between the transistor acting as a driver and the one transistor can also be arranged in series. This can be designed as a PMOS transistor.
  • the gate acting as a driver transistor, may be connected to ground potential, so that this transistor may also form a switch of the driver circuit.
  • the driver circuit operates as an electrical voltage source for the organic light emitting diode.
  • the circuit arrangement for each individual organic light-emitting diode can be produced in an integrated realization as a CMOS circuit on a very small area. It enables a high resolution of the display.
  • the maximum brightness of the image (full scale) is adjustable over several orders of magnitude from ⁇ 100 Cd / m 2 to well over 10000 Cd / m 2 .
  • the circuit arrangement for the use of displays for project applications and for applications in very bright environment outsidedoors in clear skies, aircraft cockpit, etc.
  • very dark environment night, closed by daylight rooms, etc.
  • the representation of gray levels or colors can be realized via pulse width modulation so that the linearity of the input image signal to the displayed image is not influenced when the maximum brightness is changed.
  • the image information can be stored digitally in each circuit arrangement assigned to an organic light-emitting diode.
  • the resolution per color and pixel depends on the realization and can typically be 6 or 8 bits, but also more.
  • the voltage drive capability here is the maximum allowable electrical voltage difference across the emitting organic light emitting diode between the electrical voltage across the organic light emitting diode in the maximum controlled state (highest brightness value) and the electrical voltage across the organic light emitting diode in the dark state (lowest brightness value).
  • Microdisplays with organic light-emitting diodes 5 are preferably constructed such that they contain light-emitting organic layers (OLEDs) on the top metal level of a CMOS substrate in the case of electrical current flow. These can be individually activated locally, ie as so-called pixels, by electrical current flowing locally through the organic light-emitting diode 5 via an electrode of the organic light-emitting diode 5. Underneath the electrode, active and passive components (usually transistors and capacitors), which take over the control of each individual organic light-emitting diode 5, can be located in a matrix-like pixel cell arrangement. In FIG. 1 the principle cross section through an OLED microdisplay is shown.
  • OLEDs light-emitting organic layers
  • the image input data is received by an electronic control unit. This routes the data to the column driver Next, which caches the image data for a picture line.
  • the line to be described is then selected via a line driver and described with the image data buffered in the column driver. According to this principle, all lines of the matrix arrangement are sequentially programmed with their corresponding image content. Subsequently, the description of the image data of the first line for the subsequent image is started.
  • the transmission of the image data from the controller to the column driver, the intermediate storage in the column driver and the programming of the matrix is usually realized with digital signals.
  • Each pixel cell may be subdivided into subpixel cells, each subpixel cell being responsible for storing and displaying a primary color of the display.
  • the arrangement of the primary colors can, as in Figure 3 and FIG. 4 represented, realized. But there are also other realizations conceivable.
  • Each of these subpixel cells represents a single organic light emitting diode 5, which should be separately controllable.
  • each circuit arrangement for the activation of each organic light-emitting diode (subpixel cell) 5 is composed of three circuit parts. These are a memory circuit (pixel memory) 10, a sense amplifier 20 and the actual driver circuit 30 for the individual organic light emitting diodes 5.
  • the memory circuit 10 is made from as many memory cells as the color depth (in bits) of the respective color requires. Usually these are 5, 6 or 8 memory cells or bit color depth.
  • FIG. 5 the memory circuit 10 for a single organic light emitting diode 5 or a subpixel cell is shown schematically.
  • the individual memory cells of the memory circuit 10 each consist of a capacitor and two switches, which can be realized as transistors. For miniaturization, the capacitor can also be implemented as a transistor with shorted drain and source, as shown in FIG FIG.
  • the arrangement for a pixel cell with four organic light emitting diodes 5 of six bit color depth is shown in FIG FIG. 8 shown.
  • the hatched Rectangles represent the memory, wherein the corresponding programming line (eg: W0) and the corresponding readout line (eg: E0) are indicated for the memory circuit 10.
  • the sense amplifier 20 is used, which after FIG. 5 for each organic light emitting diode 5 is present.
  • the sense amplifier 20 in this example consists of two negative feedback inverters 21 and 22, which can be separated from the electrical operating voltage supply (VSS and LVDD) via two switch forming transistors 23 and 24. Furthermore, the inputs and outputs of these inverters 21 and 22 are prechargeable via two transistors 25 and 26 as a switch (activation with the signal Pre) with an electrical voltage Vpre.
  • the reading of the image information can, as in FIG. 9 shown, graphically illustrated, in three phase successes. These are the pre-charge phase (precharge), the charge phase (load) and the emitter phase (emit).
  • the inverters 21 and 22 are disconnected from the operating voltage lines (LVDD and VSS). Thereafter, the nodes V SenseIn 27 and V SenseOut 28 are precharged to the voltage V Pre . Subsequently, the memory circuit 10 to be read out is activated via the corresponding switch (Emit), whereby the voltage at the node V SenseIn 27 is either increased in the direction LVDD (with stored high value) or lowered in the direction VSS (at low value).
  • the readout amplifier tilts 20 depending on the memory value in one of the two stable states, so that at the output V SenseOut the negated signal from the previously read memory circuit 10 is applied and the stored value in the memory circuit 10 can be renewed simultaneously.
  • the output of readout amplifier 20 activates driver circuit 30 for organic light emitting diode 5 and electromagnetic radiation (light) is emitted.
  • Each bit memory is read out one after the other and the content displayed accordingly.
  • the duration of the Emittierphase is different lengths.
  • the actual image information is reconstructed by temporal integration of the emitted light in the eye of the beholder.
  • the memory circuit 10 and the readout amplifier 20 of an organic light-emitting diode 5 consist exclusively of low-voltage transistors (NMOS and PMOS transistors) and require two operating voltage lines LVDD and VSS.
  • the third part of the entire organic light emitting diode circuit 5, the driving circuit 30, is shown in FIG FIG. 10 illustrated in an exemplary embodiment.
  • the driver circuit 30 consists of two low-voltage PMOS transistors M Drive 1 and M swi 2, a low-voltage NMOS transistor M Nswi 3 and only one medium or high-voltage PMOS transistor M MV 4 with a separate Well terminal.
  • the driver circuit 30 requires only the operating voltage lines LVDD and VSS and a common supply for the cathode voltage V cathode of the organic light emitting diodes 5 for the entire display.
  • the peculiarity of this driver circuit 30 is the fact that V cathode may be more negative than VSS (ground).
  • FIG. 11 shows a second variant of a usable in the invention driver circuit 30.
  • an additional switch M Goff with another transistor 7, which is designed as a low-voltage PMOS transistor), and can be used for the shutdown of the respective organic light-emitting diode 5, used.
  • the further transistor 7 is also connected in series.
  • This deactivation function can be used, for example, if additional optical sensors (not shown) are integrated on the microdisplay chip and these are optically decoupled from the microdisplay (and the emitted light of the organic light emitting diodes), as described in US Pat DE 10 2006 030 541 A1 is described. such optical sensors can be eg cameras.
  • V DriveIn connected to V SenseOut of the readout amplifier 20 can be distinguished for two operating modes of the entire circuit arrangement .
  • the driver circuit 30 is activated.
  • the transistor M NSWi 3 is high-impedance and the transistor M Swi 2 conductive and an electric current I OLED can flow from LVDD through the transistors M Drive 1, M Swi 2 and M MV 4 in the organic light emitting diode 5.
  • the size of the electric current depends on the electrical voltage V Drive and can be set over several decades. In this case, the linearity of the image representation is not affected, since the representation of color gradations / gray levels on the previously described pulse width modulation can be realized.
  • the driver circuit 30 When the input voltage signal is switched to LVDD (High), the driver circuit 30 is disabled. In this case, the transistor M Swi 2 is high-resistance and the transistor M NSwi 3 is electrically conductive. The transistor M Nswi 3 switches the node V SMV to VSS and protects the actual current source transistor M Drive 1 and the transistor M Swi 2 from electrical overvoltages (in this case voltages less than VSS). Thus, only a very small electrical leakage current can flow through the transistor M MV 4 (high-impedance) and the electric current through the organic light-emitting diode 5 becomes so small that it no longer lights up.
  • the electrical voltage difference across the organic light emitting diode 5 (V anode - V cathode ) is thus smaller than the voltage applied to the organic light emitting diode 5, electric current flow, because the voltage V anode approaches the voltage V cathode .
  • a special case for operation is when the voltage V Drive is switched to VSS.
  • the transistor M Drive 1 operates as a switch and the driver circuit 30 operates as an electrical voltage source for the organic light emitting diode 5, which provides the electrical voltage LVDD in the on state.
  • the driver circuit 30 can therefore be used both as an electrical current and as a voltage source.
  • the driver circuit 30 can drive a maximum electrical voltage difference across the organic light emitting diode 5, ranging from 0 volts in the off state to (LVDD-V cathode ) in the on state.
  • the electric voltage V cathode (less than 0 volts) of the amount may be at most as large as the allowable drain-source voltage of the transistor M MV 4.
  • a voltage swing of 5 V up to 15 V at the organic light-emitting diode 5 can thus be realized from the on-off state.
