摘要： An electroluminescent display comprising a mask defining the information to be displayed and an electroluminescent (EL) backlight. The mask compress a layer (13) of physically-stabilised liquid crystal switchable to define the information to be displayed mounted in front of an EL layer (16) of the backlight. At least one pair of electrodes (12, 20) are arranged to generate, in use, an electric field across both the EL layer (16) and the LC layer (13). A barrier layer (15) is provided between the LC layer (13) and the EL layer (16) that restricts migration of liquid crystal from the LC layer (13) to the EL layer (16).

摘要： An electroluminescent display comprising a mask (13) defining the information to be displayed mounted in front of an electroluminescent EL material backlight (16). Furthermore, the display comprises a transparent front layer as substrate (11), a transparent electrically - conductive film as front electrode (12), an optional insulating interlayer (10), an electroluminescent / phosphor material (17), an optically - reflective electrically - insulating lager (19), and an elctrically - insulating lager (19), and an electrically - conductive film as rear electrode (20). The mask (13) comprises a layer of liquid crystal vesicles (14) encapsulated in a curable polymer matrix (15), where the polymer chains of the polymer matrix (15) have been cross-linked by exposure to radiation. Preferably the polymer matrix is a UV curable polyurethane. The invention also concerns a method of making such a display.

摘要： A drive circuit for driving electroluminescent (EL) segments and polymer dispersed liquid crystal (PDLC) segment of a display. The circuit may include a flyback converter for generating an A.C. output voltage, a first switching circuit for selectively connecting the output voltage to the EL segments, and a second switching circuit for selectively connecting the output voltage to the PDLC segments. In order to drive the EL segments and PDLC segments at the required frequencies, the polarity of the output voltage applied to the PDLC segments is swapped at a frequency lower than the frequency at which the polarity of the output voltage is swapped for the EL segments. In this way, only a single high voltage power supply is required to drive both the EL and PDLC segments.

摘要： An electroluminescent display of the type having a switchable electroluminescent (EL) material backlight (16) mounted behind a mask (13) defining the information to be displayed, in which display the mask is constructed as a layer of physically-stabilised Liquid Crystal (LC) material (14) switchable to define the information to be displayed; and the LC mask and the EL backlight are constructed as a single entity. The LC mask may be directly formed on the EL backlight, or there may be an insulating interlayer (10) between LC mask and EL backlight. The LC mask and EL backlight may be held between a common pair of electrodes (11, 20).

摘要： A membrane switch comprising a flexible membrane (32, 38, 138) forming a movable part of the switch, the flexible membrane comprising an electroluminescent display (38, 138). More specifically, a switch of the non-latching type, typically for use with a flexible electroluminescent display, which switch comprises: an underlying circuit layer (31, 131) carrying a circuit (34, 35, 134, 135) which the switch is to operate, the circuit being broken by a gap (36, 136) which the switch is to close; a resiliently-deformable contact layer (32, 38, 138), mounted to face the circuit layer's circuit face, the contact layer's circuit-facing surface carrying a conductive bridge portion (37, 137) aligned with- the gap, which bridge portion can be resiliently pushed into operative contact with the circuit layer to close the gap therein so long as an applied pushing force (F) is present; and spacing means (33, 133) that keeps the two layers apart in the absence of any applied force pushing them together. The contact layer is typically an electroluminescent display (39, 138). The spacing means is preferably integral with either of the contact or circuit layers, and is advantageously thermoformed in the contact layer.

摘要： Certain materials are electroluminescent, and this electroluminescent effect has been used in the construction of backlights for displays. Such a backlight commonly consists of a transparent front layer (11) known as the substrate carrying over its rear face a transparent electrically-conductive film (12) forming the backlight's front electrode and covered by a layer of electroluminescent/phosphor material (13) over the rear face of which is a high-dielectric layer (16) bearing on its rear face a conductive film (17) forming the back electrode. The whole is positioned behind a mask (18) that defines whatever characters the display is to show. This use of a mask has some disadvantages, some of which can be overcome by utilising an array of suitably shaped individual electrodes (21) instead of a continuous one; however, this itself has drawbacks, since the lead (22) to each electrode acts as an electrode in its own right, activating the phosphor to show faint but distracting additional illumination. The invention deals with this problem of track-derived tails; it proposes firstly that the electroluminescent material itself be shaped into discrete areas (43) each tightly matching in shape and size the relevant individual shaped back electrode (21), and secondly (or in addition) that there be used a shield layer (71) of electrically-conductive material shaped and sized as a negative of the shaped area back electrode (21) and positioned as an intermediate electrode between and aligned with the shaped area electrode (21) and the electroluminescent material layer (43), and given the same electrical potential as the front electrode (12).

摘要： A control circuit for an electro luminescent display in which a flyback converter and an H-bridge are used to provide a high voltage alternating current to a capacitive load from a low voltage DC source. Each time the polarity of the capacitive load is reversed, the capacitive load discharges. This high voltage discharge is stored on a low voltage capacitor and subsequently used as an auxiliary power supply to power the switching elements of the control circuit.

摘要： A drive circuit of a display device comprising a capacitive display (Hl) and a further display H2. The drive circuit is arranged to provide to the capacitive display, such as an electroluminescent display, an AC drive signal at a first, high voltage from a low voltage power source such that, in use, the drive circuit is repeatedly charged and discharged. The drive circuit is further arranged such that, when the capacitive display discharges, a discharge current from the display is supplied at a second, lower voltage to the further display. In the way energy from the capacitive display is used to drive a further display rather than being discarded.
