Display sub-assembly for an HVAC controller
First Claim
1. An HVAC controller, comprising:
- an output port;
the HVAC controller configured to provide HVAC control signals to the output port for controlling one or more HVAC components;
a printed circuit board; and
a display sub-assembly comprising;
a frame secured relative to the printed circuit board;
the frame including a front side facing away from the printed circuit board and a back side facing toward the printed circuit board, the frame including side walls extending between the front side and back side, with the side walls defining a space;
a display positioned at least partially within the space defined by the side walls of the frame;
a light guide positioned at least partially within the space defined by the side walls of the frame, the light guide positioned between the display and the printed circuit board;
the frame having one or more back stop features that stop the light guide from sliding out of the back side of the frame;
the frame having one or more front stop features that stop the display from moving out of the front side of the frame; and
the frame having one or more reflecting features that are each shaped to receive incident light entering from the back side of the frame, and to reflect and distribute the received incident light across at least part of the light guide and thus the adjacent display.

Abstract
An HVAC Controller including a printed circuit board (PCB) and a display sub-assembly. The display sub-assembly may include a frame, a display, and a light guide. The frame may be secured relative to the PCB and may have a front side facing away from the PCB and a back side facing toward the PCB. The frame may include one or more side walls that may extend between the front side and the back side, where the side walls may define a space. The display and the light guide may be positioned at least partially within the space and the light guide may be positioned between the display and the PCB. The frame may have one or more back stop features and one or more front stop features that stop the light guide and the display from sliding out of the back side and front side of the frame, respectively.

15. An HVAC controller, comprising:
-
an output port;
a controller configured to provide control signals to the output port for use in controlling one or more HVAC components;a printed circuit board having one or more light sources; and a display sub-assembly connected to the printed circuit board, the display sub-assembly comprising; a display; a light guide situated behind the display for providing a back-light to the display; a frame secured relative to the printed circuit board, the frame having a back side facing the printed circuit board and a front side; the frame holding the display and the light guide, with the light guide positioned toward the back side of the frame relative to the display; and the frame including two or more spaced reflective features that are each at least partially cone-shaped and configured to receive light from the one or more light sources of the printed circuit board and to distribute the received light across at least part of the light guide and thus across at least part of the display. - View Dependent Claims (16, 17)
