The present invention relates to a display apparatus, a pixel array and a manufacturing method thereof, and more specifically, the present invention relates to a pixel array and a display apparatus with a display medium module and a manufacturing method thereof.
With the advancement of technology and time, users are getting more demanding about visual display and voice, and require multimedia devices with the advantages of compactness, high contrast, high dynamic, high color saturation, high aperture ratio, large-sized panel, low cost and low power consumption, high quality, multi-faceted display, easy maintenance and good sound quality and other advantages of multimedia devices.
The display part of the current multimedia device can be divided into self-luminous and non-self-luminous ways to achieve the function of image display, and the liquid crystal display is the main way of non-self-luminous flat panel display device, wherein the amount of light passing through a liquid crystal medium is modulated by controlling the voltage of the upper and lower electrodes of the liquid crystal medium. The effect of color display is achieved with further employment of a color filter layer, a polarizer and some functional optical films, and backlight, etc.
Self-luminous flat panel display may be categorized into field emissive display, plasma display, electroluminescent display, photoluminescent display, organic light-emitting diode display and so on. In an organic light-emitting diode display (OLED), light-emitting polymers are deposited between an upper electrode layer and a lower electrode layer. With further employment of a conductive layer of electrons and holes, and light display is generated by adding the electric field to move the carrier, resulting in electrons and the hole carrier recombination phenomenon. In comparison, an organic light-emitting diode display device is characterized by its wide viewing angle, fast responding speed, thin panel and flexibility; further, it requires neither backlighting nor color filter and may be made large-sized.
The display panel of both LCD and OLED devices has a plate of transparent glass for a substrate, directly and sequentially forming a thin-film transistor, a lower electrode layer, a display medium layer, an upper electrode layer and others thereon. The thin-film transistor may control the voltage or current imposed on the upper electrode layer and/or the lower electrode layer to control the state of the display medium. Since it is necessary to directly and sequentially form a thin film transistor and an electrical conduction pattern on the glass substrate, whereon will be relatively compressed the effective area of pixel unit, and difficult to achieve high aperture rate of pixel unit.

The display medium module 1U comprises at least one pair of electrodes and a display medium 105. The pair of electrodes includes a first electrode 101PE and a second electrode 102RE, and the first electrode 101PE and the second electrode 102RE are separated from each other and may face each other. The display medium 105 is disposed between the first electrode 101PE and the second electrode 102RE. The first electrode 101PE and the second electrode 102RE may also be referred to as a pixel electrode and a pixel corresponding electrode, and may be a non-transparent, partially transparent and/or transparent electrode (e.g. formed of a metal oxide, a nano silver wire, a conductive polymer, carbon nanotubes and graphene). Electrical energy may be imposed on the first electrode 101PE and the second electrode 102RE to change the magnitude and/or the direction of the voltage, current, inductance, capacitance, electrical field, and magnetic field between the first electrode 101PE and the second electrode 102RE and one of the combinations thereof.
The first electrode 101PE may also be electrically connected to the active switching element 116 (e.g. via the electrode 116E of the active switching element 116 and/or another set of electrical conductors 118). The active switching element 116 may control whether electrical energy is to be imposed on the first electrode 101PE and/or the second electrode 102RE.
The display medium 105 may also be called light modulation medium. Its state may be changed via the first electrode 101PE and the second electrode 102RE to control the amount of light passing through (or modulate the properties of light). Specifically, the active switching element 116 may control the electrical energy imposed on the first electrode 101PE and/or the second electrode 102RE, causing the voltage, current and electric field and so on between the first electrode 101PE and the second electrode 102RE to change, which causes the state of the display medium 105 to change. In the case of a display medium 105 made of non-self-luminous liquid crystal, change in the state of the display medium 105 means torsional rearrangement of the liquid crystal molecules. In the case of a display medium 105 made of self-luminous organic light-emitting diode, change in the state of the display medium 105 means by the applied electric field magnitude to move the carriers for inducing the electrons and the holes carrier recombination phenomenon, to produce light intensity and color. The type of the display medium 105 is relevant to the configuration of the first electrode 101PE and the second electrode 102RE.

The first electrode 101PE may be disposed on the first substrate 101PS, the second electrode 102RE may be disposed on the first substrate 101PS and/or the second substrate 102RS (depending on the type of the display medium 105), and the display medium 105 may be disposed between the first substrate 101PS and the second substrate 102RS (or, when the display medium module 1U comprises only one of the first substrate 101PS and the second substrate 102RS, the display medium 105 may be disposed on the first substrate 101PS and the second substrate 102RS). The active switching element 116 may be disposed on the first substrate 101PS and/or the second substrate 102RS, but not directly manufactured on the first substrate 101PS and/or the second substrate 102RS; that is, the active switching element 116 is independent after separately manufactured before being assembled to the first substrate 101PS and/or the second substrate 102RS. Further, the active switching element 116 may be disposed on one of the upper and lower surfaces, the inside, the groove 109GV, the perforation 109TV, and the combination of the first substrate 101PS and/or the second substrate 102RS, so that the pixel aperture ratio of the first electrode 101PE is less compressed by the active switching element 116.

The control signal line 1G, the data signal line 1D, the first electrode 101PE, and/or the second electrode 102RE may be located in the same horizontal layer or different horizontal layer of the first substrate 101PS and/or the second substrate 102RS.

The technical content of pixel units 1A according to other embodiments of the present invention is described below. The technical content of the pixel unit in each of these embodiments may be cross-referenced, so identical description is omitted or simplified.
