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 1.3x1018 to 7.5x1018 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： 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 TFTs on polymer substrates. Crystallisation and hydrogenation of the semiconductor layer can be executed in the same irradiation step.

摘要： A method of forming shaped structures in liquid crystal display cells, comprises applying a photosensitive layer (6) to a transistor plate (2), and forming the shaped structures on the photosensitive layer in a photolithographic process using a grey-tone photo mask (7, 21). This mask comprises at least one region of semi-transparent material (8, 16, 18), the degree of transparency of which is dependent on the optical band gap of the material.

摘要： A display device comprises an array of rows and columns of pixels disposed over a common substrate. Each pixel comprises a display pixel element having a stable drive state in which the optical characteristics remain substantially constant and a drive circuit for controlling the voltage applied to the display pixel element. An optical sensor arrangement of each pixel (PR1, R2) detects an optical signal dependent on the setting of the display pixel element, and the drive circuit comprises an optical feedback control system which is arranged to drive the display pixel element to the stable display state in response to an applied input pixel voltage and an output of the optical sensor arrangement, the optical characteristics being varied before the drive of the display pixel element reaches the stable state and being held substantially constant once the stable state has been reached. This approach removes the need to apply complicated voltage control schemes to the display element. Instead, a desired brightness is loaded into the pixel (as a voltage level), and optical feedback within the pixel is used to achieve the desired brightness level.

摘要： A method of manufacturing an active matrix display device involves manufacturing a first substrate arrangement comprising a rigid glass substrate and an overlying plastic substrate. Pixel circuits are formed over the plastic substrate. The rigid glass substrate (12) is only removed from the plastic substrate after the mounting of the active and passive plates of the display into display modules (10). This method enables substantially conventional substrate handling, processing and cell making to be employed, for example in standard AMLCD factories, with only minimal extra equipment needed. A more general manufacturing method is also disclosed for fabricating TFTs on a spin-on plastic layer.

摘要： A co-planar thin film transistor, TFT (22), and a method of fabricating the same, in which an additional insulating layer is provided on the source contact (30) and the drain contact (32) and defined such that a first region (34) of the additional insulating layer occupies substantially the same area as the source contact (30) and a second region (36) of the additional insulating layer occupies substantially the same area as the drain contact (32). This tends to provide a reduction in the gate (62) to source capacitance, and the gate (62) to drain capacitance. In some geometries this can be achieved without any additional masks or defining steps.

摘要： A display device has a plurality of pixels, each pixel having a current-driven display element (2) coupled between a first conductive layer (28) and a second conductive layer (27), the second conductive layer (27) being coupled to a current supply (26) via a switchable device (12) having a thin film component (122) on a first area of a substrate (120). Each pixel further has a first capacitive device having a first capacitor plate (132) on a second area of the substrate (120), the first capacitor plate (120) being conductively coupled to the thin film component, a second capacitor plate (133) and a first insulating layer (130) between the first capacitor plate (132) and the second capacitor plate (133). Stacked on top of the first capacitive device is a second capacitive device sharing the second capacitor plate (133) with the first capacitive device, the second capacitive device further comprising a third capacitor plate comprising at least a part of the second conductive layer (27), and a second insulating layer (140) between the second capacitor plate and the third capacitor plate. This arrangement benefits from larger capacitances for the first capacitive device and the second capacitive device, making them more robust against the influences of parasitic capacitances.

摘要： A method of manufacturing a colour active matrix display device comprises forming islands over a rigid carrier substrate, forming a plastic substrate over the rigid carrier substrate, forming an array of pixel circuits over the plastic substrate and forming a display layer over the array of pixel circuits. The rigid carrier substrate is then released from the plastic substrate and the plastic substrate then has channels defined by the islands. These are filled to define colour filter portions. The formation of a plastic substrate on a rigid carrier, with the use of a subsequent lift off process, enables the circuit arrays to be made on very thin plastic sheets. The colour filters can then be made on the outside of the LC cell. Depressions are formed in the plastic substrate registered to the circuit array, and these are filled in with colour filter material, for example by ink jet printing.

摘要： An active plate for a liquid crystal display has an insulating layer (76) arranged as a plurality of columns, each insulating layer column overlapping the pixel electrodes (12) of two adjacent columns of pixels. An opaque conductor layer is formed over the substrate and patterned to define column conductors (34) on top of the insulating layer, and source and drain electrodes for the transistor on top of thin film transistor layers (66). Thus, an insulating layer (76) is defined beneath the column conductors (34), so that it lies between the crossing row and column conductors. In addition, the columns of insulating layer (76) overlap adjacent pairs of pixel electrodes (12), so that the column conductors can overlap the pixel electrodes, thereby increasing the pixel aperture. The transparent pixel electrodes (12) are, however, the first layer to be deposited. This gives advantages in process simplification and corresponding cost reduction for manufacture of high quality active matrix LCD (AMLCD) displays.

摘要： A post spacer (25) for a liquid crystal cell (26) is formed using colour filter material. At least a portion (15a) of the post spacer (25) and a corresponding pixel colour filter (15b) are defined from a layer of colour filter material (15) using photolithography, in which a photomask (8) comprising a pattern of transparent, half-tone and opaque regions is used to define structures with two different thicknesses t1, t2 simultaneously. The use of a half-tone photomask (8) allows the thickness of the post spacer portion (15a), and, therefore, the eventual height of the post spacer (25), to be defined independently of the thickness of the colour filter (15b). The post spacer (25) may be formed using half-tone photomasks (8) to define more than one layer of colour filter material (15, 23), allowing the ratio t1/t2 to remain within a predetermined limit. The post spacers (25) are preferably located away from thin film transistors (TFTs) (31) and at intersections of row and column electrodes (32, 33).
