摘要:
The present invention discloses an electronic device (100) comprising a substrate (10) carrying an electrode structure (12); an electro-optical stack (90) at least partially covering the electrode structure (12), the electro-optical stack comprising a stratified polymer layer (44), a further substrate (20) and an electro-optical material (32) sandwiched between the polymer layer (44) and the further substrate (20); and an adhesive layer (60) between the substrate (10) and the electro-optical stack, as well as a method for producing such an electronic device (100), in which the electro-optical stack (90) and the substrate (10) are prepared in separate processes and combined by an adhesive layer (60). This improves the yield of such an electronic device (100), because a production error in one of the components no longer leads to the loss of the whole electronic device (100). Also, sensitive components on the substrate (10) such as polymer based TFTs, are protected from exposure to the processing steps of the electro-optical stack (90).
摘要:
Display units (1) comprise display panels (90) which are divided into active parts and inactive parts. The driving of an entire display panel (90) requires a minimum amount of time, which amount of time increases with an increasing number of rows and columns. By providing data signals to the pixels (11) located in active parts, and by supplying reference signals simultaneously to pixels (11) located outside the active parts, most of an amount of time available in a frame period is used for the active part, and, for a given frame period, the number of rows and columns of the display panel (90) can be increased. Respective parts are made active during respective 3 periods. A part may comprise a group of columns (ADG, BEH, CFI) and/or a group of rows (ABC, DEF, GHI). The display panel (90) may comprise multiplexing circuitry (50) and/or shift register circuitry (60) to reduce the number of connections between the display panel (90) and the rest of the display unit (1).
摘要:
The electronic device (1) of the present invention has a carrier (10) with a plurality of discrete electro-optical elements (110, 130, 150) mounted on the surface of the carrier (10). The electro-optical elements (110, 130, 150), which cover respective parts of the electrode structure (12) on the surface of the carrier (10), each have a polymer layer (114, 134, 154), which encloses an electro-optical material (102, 122, 142) between the polymer layer (114, 134, 154) and the surface of the carrier (10). The discrete electro-optical elements (110, 130, 150) have been formed by the individual deposition of discrete droplets of a liquid comprising the electro-optical material and a polymer precursor followed by exposure of the droplets to a stimulus triggering the polymerization of the polymer precursor.
摘要:
Provided is a method of manufacturing a field effect transistor with an organic semiconductor, and particularly a device comprising a plurality of field effect transistors with an interconnect structure. Herein, use is made of three photolithographical masks for four layers. Thereto, the transistor is provided in a top-gate structure, and the organic semiconductor layer (307) and the dielectric layer (309) are structure and patterned together. The semiconductor layer (307) and the dielectric layer (309) may be removed from areas not associated with field effect transistors (300) or with crossing conductors of the first and second conductor layer (303, 305, 501).
摘要:
A portable device is provided having a touch sensitive display (100) comprising an active matrix display element (101) and a touch sensitive element (103). The touch sensitive element (103) is disposed on the viewer distal side of the active matrix display element (101) thereby not affecting the display properties. The touch sensitive element (103) comprises a first and second conductive layer (113, 115) each having a plurality of conductors. The conductive layers (113, 115) sandwich a pressure sensitive layer (117) which modifies an electrical conductivity between two conductors of the two conductive layers (113, 115) in response to a pressure point resulting from an applied pressure. Thus, accurate position detection is achieved. The conductors may be aligned with the active matrix and the requirement for calibration may be obviated.
摘要:
A (display) device (31,4,5) contains multiple panels (3,7) like e.g. displays. Every display can be used to display its own content and can be rolled out of a sub-housing (5) like e.g. a cartridge separately. In different configurations the same cartridge can be arranged in such a way that the panels are used for a separate functionality or multiple display panels form one big screen.
摘要:
A gray level compensation mechanism is proposed for flexible displays. Flexible displays exhibit cell gap variations upon bending. The cell gap is measured during operation of the display (capacitive, poezoelectric). The pixel voltage is adjusted according to the measured cell gap. This results in a gray level that is independent of the local bending radius.
摘要:
A display employs an arrangement of a matrix of pixels (30), and a column driving circuit (10) including an array of fixed level data drivers (30) for generating a drive waveform that is applied to the matrix of pixels (30) during an image update period. A power supply (VPS) for each fixed level data driver (11) is set to a base voltage (V0) during a first phase (P1) of a driving portion (DP) of the image update period, and the power supply (VPS) of each fixed level data driver (11) is switched from the base voltage (V0) to a transitional voltage (V1) in response to a transition from the first phase (P1) of the driving portion (DP) to a second phase (P2) of the driving portion (DP). The base voltage (V0) will either be less than or greater than the transitional voltage (V1).

摘要:
An electronic device (10) comprises a substrate (100) carrying a single electrode structure (120) and a plurality of electro-optical elements (140; 160, 180). The plurality of electro-optical elements (140, 160, 180) at least includes a first electro-optical element (140) covering a first part of the electrode structure (120), the first electro-optical element (140) comprising a first electrooptical material with a first transmission/voltage response characteristic and a second electro-optical element (160) covering a second part of the electrode structure (120), the second electro-optical element (160) comprising a second electro-optical material with a second transmission/vokage response characteristic. Consequently, the various electro-optical elements (140; 160 180) can be individually controlled with a single electrode structure by applying variable voltages.
