    摘要: An electronic device (70) comprises a thin film transistor (TFT) (9,59), the TFT including a channel (16) defined in a layer of polycrystalline semiconductor material (10,48). The polycrystalline semiconductor material is produced by crystallising amorphous semiconductor material (2) using metal atoms (6) to promote the crystallisation process. The polycrystalline semiconductor material (10) includes an average concentration of metal atoms in the range 1.3×1018 to 7.5×1018 atoms/cm3. This enables polycrystalline semiconductor TFTs to be formed with leakage properties acceptable for use in active matrix displays using a metal induced crystallisation process of duration significantly less that previously thought necessary. Furthermore, this process duration reduction facilitates the reliable fabrication of poly-Si TFTs having bottom gates formed of metal.

    摘要: An active plate (2) for an active matrix display device (16), the active plate (2) comprising a substrate (4), a pixel area (6) and an adjacent drive circuit area (8). Both areas include polycrystalline silicon material formed by a process in which a metal is used to enhance the crystallisation process (MIC poly-Si), but only the MIC poly-Si in the drive circuit area (8) is subjected to an irradiation process using an energy beam (10). TFTs are fabricated with MIC poly-Si which have leakage currents in the off state sufficiently low for them to be acceptable for use as switching elements in the pixel area of matrix display devices. As only the drive circuit area (8) need be irradiated to provide poly-Si having the desired mobility, the time taken by the irradiation process can be significantly reduced.

    摘要: A method of manufacturing an electronic device comprising a thin film transistor (42), comprises forming a hydrogen-containing layer (22) over a semiconductor layer (10; 20), irradiating the hydrogen-containing layer so as to hydrogenate the semiconductor layer, and then forming electrodes (24; 26, 28) over the semiconductor layer. A short diffusion length and direct path is provided for the hydrogen thus allowing rapid hydrogenation of the semiconductor layer using relatively few, high-fluence laser pulses. The supporting substrate (12) is not heated significantly making the method particularly useful for TFFs on polymer substrates. Crystallisation and hydrogenation of the semiconductor layer can be executed in the same irradiation step.

    摘要: The display panel (1) has multiple picture elements (2), each picture element (2) having respective neighboring picture elements (2′). The picture elements (2) have a first electrode (3) and a second electrode (4) for the application of a potential difference between the first and the second electrode (3,4), and electrochromic material (5), which is present between the first and the second electrode (3,4). Electrical charge contained by the electrochromic material (5), induced by the potential difference, determines the color of the picture element (2). Color changes are provided by varying the electrical charge. Crosstalk, being coloration of neighboring picture elements (2′) when a picture element (2) is addressed, is adjustable by third electrodes (6) which adjust electrical currents between the picture element (2) addressed and their respective neighboring picture elements (2′).

    摘要: An active matrix display device has pixels each with a light-sensitive device (84) for optical feedback functions. Each pixel has a light blocking structure (100) formed from the thin film layers of the display substrate in the proximity of the light-sensitive device (84) and substantially at the level of an input surface of the light sensitive device. This structure prevents the passage of light (g) to the light sensitive device from a substantially lateral direction.

    摘要: An EL device comprising a substrate (11), a light emissive structure comprising three series connected LEDs on the substrate (LED 1, 2, 3). Considering the diode LED1, it comprises organic light emissive material disposed (16-1) between an underlying ITO anode (12-1) and an overlying cathode (17-1) that is electrically connected in series to the underlying anode (12-2) of the diode LED2 through the thickness of the organic light emissive material (16-1). The connection can be made by using a wetting agent to prevent the organic light emissive material disposed (16-1) covering contact region (19-1) on the anode (12-2) so that the overlying cathode (17-1) can make a series connection with the underlying anode (12-2).

    摘要: In an active matrix electroluminescent display device having an array of pixels, a drive transistor (22) and an electroluminescent display element (2) in each pixel are connected in series between a power line (26) for supplying or drawing a controllable current to or from the display element and a common potential line. The power line (26) and the common potential line each comprise a sheet electrode shared between all pixels of the array. In this arrangement, sheet electrodes are used both for the current supply to the EL display element and the current sink. This reduces considerably the line resistance.
