The accompanying drawings illustrate implementations of the concepts conveyed in the present document. Features of the illustrated implementations can be more readily understood by reference to the following description taken in conjunction with the accompanying drawings. Like reference numbers in the various drawings are used wherever feasible to indicate like elements. Further, the left-most numeral of each reference number conveys the FIG. and associated discussion where the reference number is first introduced.
The present concepts relate to display devices and components of display devices. Traditionally, a set of display components are secured together in a display chassis of a display device. The display chassis is then positioned in a system chassis of the display device. The system chassis can also be associated with other components, such as various sensors like cameras (e.g., visible light cameras and/or depth cameras). The sensors can then be oriented relative to the display. The present concepts can replace the display chassis and the system chassis with a single integrative display chassis. The single integrative display chassis can provide a larger effective display area (e.g. active area) for given display device dimensions. Further, the integrative display chassis can provide inherent orientation of the cameras and the display. Thus, the present implementations can provide superior display devices compared to traditional techniques and can produce these superior display devices with fewer components than traditional techniques.
Components 210-226 (e.g., LCD color filter glass 210, liquid crystals 212, LCD thin film transistor glass 214, polarizer 216, light guide plate 218, LED partial reflector 220, LED 222, LED flex/housing 224, and reflector sheet 226) can be positioned within and/or supported by the integrative display chassis 104. Additional components (e.g., display protective layer 106, touch panel assembly 202, adhesive film 204, optically clear adhesive 206, polarizer 208) can be precisely embedded and/or aligned/oriented to the integrative display chassis 104 and hence to the surface of the display 102 such that components 210-226 are oriented in light transmitting relation to one another and to the additional components.
The integrative display chassis 104 can provide structural support to the interactive surface of display 102. The integrative display chassis 104 can provide easy assembly of the display device 100A. Further, the integrative display chassis can facilitate reworking and/or removal of display 102 from the display device 100A. Stated another way, the display protective layer 106, touch panel assembly 202, adhesive film 204, optically clear adhesive 206, and/or polarizer 208 can be removed from the display device, then the integrative display chassis 104 with components 210-226 can be removed. Components can be repaired or a new integrative display chassis with associated components 210-226 can be installed. The integrative display chassis 104 can be formed of any material that can provide structural support to the display components and/or allow features to be formed therein. Example materials can include various plastics, polymers, and/or composites, among others.
The display device 100A of
Construction of traditional display device 300 involves a cumulative stack build of reflector sheet 226, light guide plate 218, polarizer 216, LCD TFT glass 214, liquid crystals 212, and LCD color filter glass 210. These components are then enclosed by a metal display chassis 302. The metal display chassis tends to be heavy, thick, and/or can cause electrical interference with antennae performance. A tape 306 is required to hold the components relative to the display chassis 302 to form an LCD module 308. The tape 306 can impart mechanical stress forces on the LCD module 308 which can induce physical deformation on the LCD module 308 (e.g., the stress forces can cause the LCD module to be non-planar or warped which poses difficulty in subsequent display construction steps) and/or cause the display device 300 to be more prone to display artifacts.
Tolerances T1 are employed between the components of the LCD module 308 and the display chassis 302 in the x and y reference directions. Additional tolerances T2 are employed between the display chassis 302 and the system chassis 304 in the x and y reference directions. In contrast, the implementation of display device 100A shown in
Furthermore, in relation to traditional display device 300, using an ultrathin glass (0.05 to 0.3 mm) or a hard plastic film for display protective layer 106, an overhang area beyond the active area (e.g., the delta between w2 and w4) needs to be supported during integration of LCD module 308 and display chassis 302 in system chassis 304 and housing 110.
Returning again to
The camera 108(1) can be positioned in this feature 228. Further, because the integrative display chassis 104 orients both the display 102 and the feature 228, the camera 108(1) can be automatically oriented by the integrative display chassis relative to the display. For instance, the integrative display chassis 104 defines the major planar surface (e.g., xy plane) and orients the camera orthogonally to the major planar surface via the orientation of feature 228. Stated another way, the integrative display chassis may have features that align the camera (or other component), for example, such that the center of the camera is in the center of a circular opening in the touch panel black border (x, y alignment), the rear of the camera housing is aligned to a precise z location (to prevent interference with another component), and the polar or azimuthal angle of the camera is set as well.
Further, some implementations can achieve a robust snap fit of the display 102 and display protective layer 106 or touch panel assembly 202 onto the display device 102 without the use of adhesives. Such a configuration can be thought of as a reworkable display device 100A that offers easy removal of display 102 from a remainder of the display device.
Further, the integrative display chassis 104 can provide display device integration to allow for a very thin display protective layer 106 with or without an integral/laminated touch panel assembly 202. The integrative display chassis 104 can provide support for the thin display protective layer where the display protective layer overhangs beyond the active area.
The curved configuration of the integrative display chassis 104 can be useful in various device manifestations, such as a smart watch or other wearable smart device, or a smart phone, among others. In this example, the integrative display chassis can define a recess into which electronic components, such as processor 610, memory/storage 612, wireless components 614, and/or a battery 616, can be positioned and protected. In this example, the recess is formed in an opposite side or surface 618 of the integrative display chassis 104 from the curved surface 602. Further, the integrative display chassis can also function as a smart watch ‘case’ (e.g. housing) thereby eliminating the need for a dedicated case and associated tolerances (e.g., between the integrative display chassis and the case).
