Problems solved by technology

Note that when repairing a device, the display module is usually completely discarded and replaced with a brand new one, which is unfortunate and wasteful considering the LCD section is still completely intact and operational in most cases

Embodiment Construction

[0015] Representative applications of apparatus and methods according to the presently described embodiments are provided in this section. These examples are provided only to add context and to aid understanding of the described embodiments. It will therefore be apparent to one skilled in the art that the presently described embodiments may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid obscuring the presently described embodiments. Other applications are also possible, such that the following examples should not be considered limiting.

[0016] As described above, there is a need for a method and apparatus for reliably and efficiently separating layers within a display module. This requirement is particularly important in view of the fact that certain layers within a display module, such as the LCD layer within a touch-sensitive display module, constitute the majori...

Abstract

Techniques are disclosed for a cutting apparatus that can be used to cut a target layer within a display module, e.g., a liquid crystal display that includes a protective cover glass. The cutting apparatus includes a platform that supports a track. The cutting apparatus also includes a linear slide that is configured to both hold the display module in place and travel along the track, where the movement of the linear slide along the track is driven by a mass that is in free fall. The cutting apparatus further includes a cutting wire, where the cutting wire is positioned relative to the target layer and oscillates to cut the target layer as the linear slide moves along the track. Additional techniques are disclosed and directed toward a method for operating the cutting apparatus described above.

Description

technical field [0001] The present invention generally relates to display modules. In particular, embodiments of the invention relate to a technique for separating one or more layers within a display module. Background technique [0002] The expansion of mobile computing devices, such as laptops, smartphones, and tablets, has produced evolutions in the design, manufacture, and capabilities of liquid crystal displays (LCDs). As is well known, conventional LCDs are composed of multiple layers, which may include a backlight, a diffuser, polarizers, color filters, and in some cases a protective cover glass. Currently, however, manufacturers of LCDs have supplemented LCDs to include new layers, such as indium tin oxide (ITO) layers, that are conductive and transparent, and enable touch input to be received and interpreted by mobile computing devices. In particular, these new layers are often sandwiched between the protective cover glass and the other layers of the LCD to create...
