The subject matter of the invention is a modular image display intended for presentation of text images, text and graphic images or graphic images of an information and advertising character, especially in public utility places. The modular image display possesses, in each module (1), luminous elements (3) configured into triangular pixels (2), which, together with an electronic matrix board (4), are tightly sealed in a strengthening protective layer (5) of plastic. The surface of the protective layer (5) on the display side, among the tops of the luminous elements (3) sticking out of it, is covered by an antireflex film (6). The control system of each module (1) is equipped with a microprocessor (8). The microprocessors of all modules (1) of the display are connected, through at least one branched power and control node (10), with a data bus (11) led from an external specialised controller (12).

A passive surface mount part (30,32,44) such as a capacitor or a resistor is employed to attach a first substrate (10) to a second substrate (12), or a semiconductor device (18) to a substrate (12), for an electrical circuit assembly. Applicable forms of substrates (10,12) include a printed circuit board such as a motherboard and a daughterboard, and applicable forms of semiconductor devices (18) include an integrated circuit. In an aspect, a low profile attachment is provided forming a planar structure. Space is conserved, signal transmission is provided, and electrical performance is increased. In another aspect, a standoff is defined between the substrates (10,12) setting the substrates apart a desired distance, compensating for any surface irregularities, increasing thermal separation, and increasing interconnect flexibility. As an application, the standoff defined between the substrates (10,12) can be utilized for a structure such as optical glass structure (28) to be situated between the substrates for use with an optical circuit assembly (26).

摘要:
A system and/or method for sensing the presence of moisture (e.g., rain) and/or other material(s) on a window such as a vehicle window (e.g., vehicle windshield, sunroof or backlite). Such techniques may be used in connection with a light sensor. In certain example embodiments, a flexible printed circuit board (PCB) includes a light sensor comprising a light sensor flip-chip, with the light sensor flip-chip including at least two light sensor arrays, and with each said sensor array being configured to sense light of a predetermined wavelength. An adhesive bonds the light sensor to the PCB. A hole is formed in the PCB and the opaque layer so as to allow the light sensor arrays to see through the hole formed in the PCB and the opaque layer. A state of the vehicle lights is settable in dependence on the light sensor. The PCB is located in or is supported by the vehicle windshield.
