A convenient frame has a stand the use of which can be selected between use in a state that the frame is hung on a wall and use in a state that the frame is stood on a table surface for displaying pictures, photos, diplomas, certificates and the like. Each rendering device has a color measurement instrument for calibrating the color presented by the rendering device. A plurality of electrically resistive elements, such as a first resistive element and a second resistive element, can be disposed on the substrate where at least one resistive element is exclusively within the non-flexible portion of the substrate and at least one resistive element is within the flexible portion of the substrate. A rotatable locking mechanism is disposed within said housing and is engageable with the first member to permit slidable movement of the first member and thereby allow slidable movement of the elongated member to different locked positions.
