Embodiment Construction

[0018] refer to figure 1 , the production of the electrophoretic display device includes the assembly of the backplane 2 and the front panel 1 . The front panel 1 comprises a microcapsule element 6 incorporating a microcapsule layer 6a and an adhesive layer therein, each microcapsule comprising a positively charged white pigment and a negatively charged white pigment on its surface. Areas of black paint. The image is produced in the display by using drive circuitry (discussed below) to control which microcapsules appear to the viewer as white areas and which particles appear as black areas to the viewer. The microcapsule element 6 is fabricated on a transparent conductive element 5 (eg, ITO), which is further formed on a transparent plastic substrate 4 (eg, PET). The plastic PET substrate comprises a thin transparent layer 5 of indium tin oxide (ITO) at the lower surface of the PET substrate 4 adjacent to the layer of microcapsule elements 6 . This ITO layer 5 is used as a ...

Abstract

A technique comprising: incorporating a front panel (1) comprising a first flexible substrate (4) for supporting a display medium (6a) and comprising an array of electronic components (9) for supporting said display medium The backplane (2) of the second flexible substrate (8) is assembled together; and by sandwiching the conductive structure (6) between the front and backplane in the region between the first and second conductive elements (5, 10) between the first and second conductive elements located on opposite sides of the front panel and the backplane, wherein the conductive structure is at least more flexible than the least flexible of the front panel and the backplane.

Description

technical field [0001] The invention relates to the assembly of two planar members of a display device. In one embodiment, the invention relates to assembling a front panel and a backplane of a display device requiring an electrically conductive connection between the front panel and the backplane. Background technique [0002] Production of a display device may include the assembly of a front panel containing a display medium and a backplane containing an array of thin film transistors for controlling the display medium. The front panel should generally also include conductive elements to which a driving voltage needs to be applied via the backplane. Although this technique is capable of producing strong and durable conductive joints, the inventors have discovered that display devices in which the back and front panels are made of organic polymer (plastic) substrates can be susceptible to damage using this technique. The effect of loss of driving voltage on the conductive...
