Some of the materials in this material are fragile and can be used to detect crack formation. These materials are particularly susceptible to cracking when the material exceeds a critical deformation limit. For example, the deformation limit of ITQ (indium tin oxide) on a polymer substrate (used for many of its properties due to its conductivity and transparency) is about 1%. It is observed that the critical deformation is wider than this. Therefore, electrical functionality may be used to limit the mechanical deflection of the final device. SUMMARY OF THE INVENTION The restricted crack mainly travels to the full failure of the line. In addition, the thin fragile layer, causing reliability problems and limiting the mounting according to a particularly useful embodiment, the apparatus and method for manufacturing an electronic component includes a flexible substrate having a bending direction, the bending The orientation allows the flexible substrate to bend. Includes multiple circuit components. Each component occupies a region of the layout on the flexible substrate, and at least a portion of the circuit components have a dominant longitudinal dimension. The major longitudinal dimension of the portion of the circuit assembly is redirected from an original layout position to be transverse to the bend direction 121703.doc 200815886 to reduce stress in the portion of the circuit assembly during bending. [Embodiment] According to a particularly useful embodiment, a display device having an optimized component orientation is provided, thereby reducing the susceptibility of the display components to I5 due to fatigue caused by the change of the curve. Although the present disclosure illustrates the flexible 'page π wave placement' in a pictorial manner, a similar principle can be applied to any device. DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present invention relate to flexible active matrix displays in which mechanical stresses, cracks, or breaks due to fragility or rigidity due to the design of the structure are limited by novel methods and layouts. In a specific embodiment, a method for designing a flexographic-moving matrix display having a tendency to reduce cracking due to machine ++, η stress reduction is proposed. For example, reducing the length of one of the lines/patterns that extend in the direction in which the display will be rolled or flexed. In a specific embodiment, a thin film transistor (TFT) is oriented to form the structure of the two τ. A 15 minute longitudinal dimension is provided perpendicular to the direction of the deflection of the flexible or flexible display. In other embodiments, the longitudinal feature is offset from its general orientation by 90, < t ^ h ^ is small during the period of the deflection of the money II. In the other embodiment I may provide less than 90. The structure of the active matrix will be anisotropic with respect to the display by the direction of ^1. The display material will be reduced because of the reduction in stress during flexing of the display: text: Description: The embodiment is suitable for flexible or flexible displays. Moments ^ - ^Teach ^ Valley can be used to reduce not only the active proactive array but also other large-area electronic devices (such as light 121703.doc 200815886 voltaic battery, memory array and integrated circuit) The rupture in the middle. It should be understood that the present invention will be described in terms of a display; however, the breadth of the present invention is far more extensive and applicable to any device that can be mounted, positioned, or: placed on a flexible substrate or The specific embodiment of the lithography process selected by the group of the singers and the selected lithography is preferably formed by using ## and thus placed on or rr. It should be noted that the lithography etching process is preferred, but the basin is merely illustrative. Other processing techniques can also be employed. ―, The study of crack formation is a statistical analysis of the formation of a crack in the conductive line: value information. To illustrate the probability of failure with the applied rattan force or "field mechanical test ... into a function of tension. Already; see 'in the reduction of curvature and rich pull the defender, the longer line will be shorter line earlier Broken clothing. For a particular curvature, the use of such τ bamboo τ + long lines is not as stable as short lines. By making the w°q meter only break one of the flexible displays or piercing after encountering a predetermined radius of curvature. The price secret is based on the principle of one of the principles. The solution is to limit the direction of the line to the direction of the line to the vertical direction of the line and may expand the m pattern with the deflection. (to the extent required) This is curved relative to the winding direction to the required minimum curvature abundance of the anisotropic property. The length L should be in the order of the length of the crack after the occurrence of t.

The Θ考Θ 2~ member circuit 202 is shown as an exemplary embodiment for displaying stress cracks in the integrated structure of a flexible display device 200. Figure 2 shows a current pixel layout 2 (9) of one of the active matrix backplanes on which circuit 202 is patterned on a number of different layers. A pixel region 201 includes a pixel that is typically one of a plurality of pixels used to generate an array of pixels in an image. The semiconductor islands 214 are patterned on a flexible or flexible substrate 203. A first metal layer 21 includes a gate 212 and a line 207. A second metal layer 2〇4 includes a data line 2〇9, a capacitor electrode 206, and a TFT electrode 208. A continuous gate dielectric and field isolation layer is not shown to allow visibility of the other layers. Further, a pixel electrode (not shown) is formed on the circuit 202 and is connected to a via hole 2〇5. Preferably, the via hole 205 and the pixel electrode (not shown) are formed by a third metal layer. FIG. 2 is shown to be optimized for flexibility with a direction of deflection in the direction of the arrow "c". A design. In this case, Ding FT 2 〗 3 and its electrodes 2 〇 8 121703.doc -10- 200815886 are straight to the flexing side " extremely high geometry. The same 1 213 has an anisotropic fm, D, and the storage grid 206 is adapted such that the longer axis (longitudinal axis) is substantially the machine axis of the vertical axis... These changes all produce very X J' The improved reliability of the display is also reduced due to the reduced rigidity and the reduced fatigue. : Reorienting the shape of the component, can it be additionally or alternatively reduced by two? : The way to change or resize it. For example, it may be red, and I degree is advantageous (e.g., 'the dimension transverse to the direction of the winding direction'). In the alternative embodiment, the direction of the deflection or the bending direction can be oriented to be advantageous. The address line is, for example, on the data line, and the gate line is 1. In another specific embodiment, the gates are The line and the data lines can be oriented in the direction of the flatness. Therefore, the direction of the winding is made perpendicular to the longitudinal dimension of the . The specific embodiments can also be adapted to other technical fields, such as in flexible large area electronic devices such as displays, photovoltaic cells, memory arrays, integrated circuits, and the like. / Figure 3 shows a diagram showing the method steps used to reduce stress, increase flexibility (flexible), and increase reliability. In step 302, a flexible display layout is provided. The layout can be either a layout design or a device that is actually manufactured. This layout design provides the ability to reposition individual components' where one device that has been manufactured can be reoriented as a whole. The layout includes a plurality of circuit components on a susceptor substrate having a curved direction. In step 3〇4, decide which component you want to reorient. This may include determining the portion of the circuit component that has a dominant longitudinal dimension on the curved side 121703.doc 200815886 7 in the layout. This decision can take into account one of the importance of a component in the layout 'the one of the dominant longitudinal dimensions, the failure tendency history of a component, and one of the materials used for the component and its characteristics. Once it has been identified - or a number of specific components due to size or one of the bending directions dominates the longitudinal dimension, causing cracking problems, reliability problems, soil stress plus tension type » »»cr } 刀刀^ ' If one of the degrees is lost, the identified component or the layout is reoriented as a whole in step 3. In step 306, at least a portion of the circuit component having, for example, a dominant longitudinal dimension in the direction of the bend is reoriented. The primary longitudinal dimension is repositioned transverse to the direction of the bend to provide reduced bending stress for the circuit rentals. In the step outline, reorienting includes rotating the layout (four) in the direction of the bend. This may include orienting the dominant longitudinal dimension to be substantially perpendicular to the bending direction or to a different transverse angle (e.g., about 45 degrees). The entire layout or individual components within the layout can be reoriented such that the dominant longitudinal dimension is transverse to the line and curvature directions for the individual components. The bow [in the MO] can resize the circuit assembly such that the dimension of the twist dimension is adjusted to reduce the main V longitudinal dimension in the bend direction. This may include expanding the component in a direction (e.g., 'perpendicular to 'L') that is transverse to the dominant longitudinal dimension. Re-adjusting the size of the dimension maintains the area of the component. The re-adjustment of the size of the pin p bar may be used in conjunction with re-orientation or may be used to replace the reorientation of some or all of the specialized circuit components.
