摘要:
The present invention is directed to display devices comprising a watermark area and a non-watermark area. The display cells in the watermark area have widths of the partition walls, heights of the partition walls, or top opening shapes, which are different from those of the display cells in the non-watermark area. The watermark aims to protect against counterfeiting or to be used for decoration purposes. The watermark is visible at certain viewing angles and/or under certain lighting conditions and it does not interfere with displaying of the regular images.

Eine Bedieneinrichtung (11) für ein Elektrogerät weist eine Anzeigefläche (12) und ein LCD-Display (13) auf zum Anzeigen von Informationen und zur Bedienung des Elektrogeräts mit Bedienelementen an der Anzeigefläche. Das LCD-Display nimmt mindestens einen Teil der Fläche der Anzeigefläche ein und weist mehrere aktive und einzeln ansteuerbare Bereiche (14a - 14e) auf. Hinter dem LCD-Display ist eine Rückseitenbeleuchtung (23) vorgesehen zur Durchleuchtung. Die Bedieneinrichtung weist einen lichtdurchlässigen Bildträger mit Bildern (20a -20e) daran auf. Die Bilder sind dauerhaft und unlösbar auf eine Druckfläche gedruckt sind, die vorgesehen ist an der Rückseite des LCD-Displays als Bildträger, oder an der Vorderseite der Rückseitenbeleuchtung zum LCD-Display hin als Bildträger oder auf einer transluzenten Diffusorfolie (18) als Bildträger, die vor der Rückseitenbeleuchtung angeordnet ist.
摘要:
The invention relates to a display screen comprising a background grid (1) with light-emitting background grid elements of a first type (2) and light-emitting or light-blocking background grid elements of a second type (3). A foreground grid (4) having completely light-transmissive foreground grid elements (5) and light-attenuating foreground grid elements (6) is arranged in front of the background grid (1) as seen from the direction of a viewer. The foreground gird (4) is arranged at a predetermined distance from the background grid (1) and is aligned in a predetermined lateral position perpendicular to the distance from the background grid (1). In such a display screen for secure representation of information, the completely light-transmissive foreground grid elements (5) and the light-attenuating foreground grid elements (6) are distributed stochastically in a ratio of approximately 50:50 in at least one foreground region of the foreground grid (4). This distribution is used as a key for coding the background grid (1). In at least one background region corresponding to the foreground region, a base coding of the background grid (1) is defined as an inverted distribution of the light-transmissive and light-attenuating foreground grid elements (5, 6), such that light-attenuating foreground grid elements (6) correspond to light-emitting elements background grid elements of the first type (2), and completely light-transmissive foreground grid elements (5) correspond to light-emitting or light-blocking background grid elements of the second type (3). In at least one selected field (7), which defines an information item and lies in the at least one background region, the distribution of light-blocking and light-emitting background grid elements (2, 3) is inverted relative to the base coding, at least in part, as a coding of the information. The lateral dimensions of the foreground grid elements (5, 6), the distance and the lateral position of the foreground grid (4) are matched in relation to the background grid (1) in such a manner that a viewer looking at the foreground grid (4) perceives the coded information in a decoded form, on the basis of a contrast difference and/or color difference in relation to those fields of the background grid (1) that are base-coded, only from one direction of view or one view angle range of up to ±50° about the view direction. The invention also relates to a method for secure representation of information on such a display screen.

摘要:
On a first light transmissive substrate (12), a first scale mark portion (24) is formed inside an opening portion (22), and on a second light transmissive substrate (32), a second scale mark portion (44) is formed. On the second light transmissive substrate (32), a first metal layer (34), a semiconductor layer (36), and a second metal layer (38) are laminated. A thin film transistor (50) is formed so as to include a part of the first metal layer (34), a part of the semiconductor layer (36), and a part of the second metal layer (38) . The second scale mark portion (44) is formed of another part of the second metal layer (38). Under the second scale mark portion (44), another part of the semiconductor layer (36) is formed so as to extend off from the second scale mark portion (44). Below the second scale mark portion (44) and the semiconductor layer (36), another part of the first metal layer (34) is formed in a size capable of shielding the opening portion (22).
摘要:
A method of forming a cell identification (201) includes forming a metal layer on a substrate, coating a photoresist material on the metal layer to form a photoresist film, exposing the photoresist film through a mask including a light-blocking pattern corresponding to a cell identification pattern, developing an exposed photoresist film, etching the metal layer using a developed photoresist film to form a metal pattern including the cell identification pattern, and irradiating a laser beam onto a symbol of the cell identification pattern. Furthermore, a display region (180) and a peripheral region (185) are defined on the substrate. An image is displayed in the display region (180). The peripheral region (185) surrounds the display region (180). The cell identification (201) formed in the peripheral region (185) includes the cell identification pattern and a mark (200) marked on the cell identification pattern. The cell identification pattern may be either a steady part (120) or a transient part (110). The steady part (120) is not changed during manufacturing processes. The transient part (110) is marked by the mark (200) during each of the manufacturing processes. The transient part (110) includes a plurality of cell identification arrays (101,103 and 105).
摘要:
Syntheses of a new blue EC monomer (ProDOT-MePro), and a new red EC monomer (ProDOP-Et2) are described. Two additional new types of EC monomers (15) based on 3,4-alkylenedioxythiophene include fluorinated EC monomers (15) and an EC monomer including silicon. EC polymer devices having more than one different color EC polymer to enable additional colors to be provided using subtractive color mixing are also described, as well as EC polymer devices incorporating a logo, image, or text, are generally obscured when the device is colored, but become visible when the device is not colored. Also described are EC polymer devices that include a cathodic EC polymer layer, a gel electrolyte, a counter electrode, and reference electrode. Working prototypes of such devices exhibit significant increases in the speed of transition of the EC device from a colored state to a transparent state.
摘要:
A weather station (100) has an MCU (151) for evaluating weather information relating to an atmospheric parameter, a sensor for sensing said parameter for subsequent processing by the MCU (151), and an LCD display (120). The LCD display (120) has a multi-layered structure including front and rear glass plates (121/122), liquid crystal material located therebetween having a number of parts (161-168), a foremost transmissive polarizer (123), and a transflective polarizer (125) behind the rear glass plate (122). There is also a colour backing (126) behind the rear polarizer (125), which has a number of regions in different colours which cover the liquid crystal parts (161-168), such that the colour regions are selectively revealed through the parts as the parts are activated, thereby displaying said weather information in colour.
摘要:
A liquid crystal display device comprises a first liquid crystal layer (15), a second liquid crystal layer, alignement layers (13,14) orientating the second liquid crystal layer, and a driving circuit (1802) driving the first liquid layer, with the alignment layers (13,14) divided into a plurality of regions whereby the orientations of the alignment layers in adjacent regions differ from each other and the regions form a recognizable pattern. This makes it difficult to recognize a displayed image from directions other than the front of the display, and allows a static pattern to be seen when the display is viewed from directions other than the front; the pattern is used to display a figure or a trade name of a product.
