Embodiment Construction

[0036] figure 1 A schematic diagram of a carrier and substrate with conductors for forming a capacitor is shown according to one embodiment of the invention.

[0037] For simplicity, only one capacitor C is shown. If display 1 is with select electrode RO (see figure 2 ) and data electrodes CO, then multiple capacitors C are required, in principle at least one capacitor C is required for each select electrode RO and each data electrode CO. Also, capacitor C can be used to divide the clock signal CLK (see image 3 ), reference levels and / or power supplies (see Figure 4 ) to display 1.

[0038] The carrier 2 comprises a carrier conductor 20 which terminates in a pad 200 and carries an input signal IS. The display 1 comprises a substrate 16 and a display conductor 12 connected at one end to a display pixel 11 and terminated at the other end in a pad 120 . The display conductor 12 is located on the side of the substrate 16 facing away from the carrier conductor 20 so that t...

Abstract

A system comprising a carrier (2) and a display (1) with a substrate (16). A display (1) comprises pixels (11) and display conductors (12) supplying display signals (DS) to the pixels (11). The carrier (2) comprises a carrier conductor (20) for carrying an input signal (IS). The display conductor (12) and the carrier conductor (20) are positioned relative to each other to obtain a capacitor (C) between the respective display conductor (12) and carrier conductor (20), thereby capacitively connecting the carrier conductor (20) The input signal (IS) on the signal is forwarded to the display conductor (12).

Description

technical field [0001] The invention relates to a system comprising a carrier and a display having a substrate and display pixels, to a display device comprising such a system, and to a display used in such a system. Background technique [0002] In order to produce matrix displays in an economical manner, the displays are usually fabricated on a substrate or motherboard. In conventional displays such as LCDs (Liquid Crystal Displays), pixels, connecting electrodes, resistive elements and transistors (if the display is an active matrix display) are present between two substrates. Usually these substrates are bonded to each other at their edges. If glass substrates are used, one glass substrate can be larger than the other to provide a space for contact latches. The contact pins are responsible for the mechanically conductive connection of the input signal to the display. For example, a contact foil comprising conductive strips may be used to make mechanical and conductive...
