Abstract

Today Computer Monitors are getting larger and larger, provide more input options, and the on-screen configuration possibilities are becoming more complex with each new model introduced. At the same time the space for placing buttons around the monitor is getting smaller and smaller with ever decreasing bezel-sizes. Additionally, due to the limited space, the limited number of buttons cannot be placed in an intuitive pattern to support on-screen configuration menu control. Additionally, many computer displays provide a USB hub through which a keyboard can be connected to the display. The USB hub of the display forwards USB signals and commands to the computer where the keyboard input is processed. In the following, we suggest to equip said USB hub with a device that analyzes the USB traffic sent from the keyboard to the computer and upon reception of a hot-key command, instead of forwarding the commands to the computer, the display's on-screen controller starts interpreting keystrokes from the keyboard to allow configuration of the display such as the contrast the source input to use, volume, etc.

Method and Apparatus to Configure Display Devices

Introduction

    Today, Computer Monitors are getting larger and larger, provide more input options, and the on-screen configuration possibilities are becoming more complex with each new model introduced.

    At the same time the space for placing buttons around the monitor is getting smaller and smaller with ever decreasing bezel-sizes (i.e., the frame around the screen). Additionally, due to limited space, the limited number of buttons cannot be placed in an intuitive pattern to support on-screen configuration menu control.

    Today monitors are primarily controlled through a Monitor Controller (MC) and a set of buttons placed on the bezel around the monitor. The MC is comprised of a microcontroller and software running thereon, receiving input from the buttons and displaying a menu on the monitor's display.

    Additionally, some monitors can be controlled through software running on a computer which is connected to the monitor through a USB interface or in case of Laptop computers potentially also through some other interface. However, such solutions require software supported by the computer connected to the display. Additionally, the software needs to constantly track keystrokes, interpret commands, and send them back to the monitor through some interface between the computer and the monitor. This configuration is shown in Figures 1 and 2.

    The difference between Figures 1 and 2 is that in Figure 1, the (optional) USB hub through which the keyboard is connected to the computer is an external device whereas in Figure 2, the USB hub is part of the monitor. It is important to note that while the USB hub is physically part of the computer it is logically disconnected from the MC and the MC's on-screen monitor configuration menu, that is, the monitor cannot be configured through the use of the normal keyboard.

Summary

    Today, many computer displays provide a USB hub through which a keyboard can be connected to the display (as depicted in Figure 2, State of the Art: Monitor with USB Hub). The USB hub of the display forwards USB signals and commands to the computer where the keyboard input is processed. In this invention we suggest to

either a) place the MC between the keyboard and the USB hub (Figure 3) or b) combine the monitor-controller with the USB hub (Figure 4), such that the input provided through the keyboard can be intercepted by the MC. Whenever the MC receives a certain key combination from the keyboard or when the monitor's on-screen menu is activated through some other means, any keystrokes provided through the keyboard will be interpreted by the MC instead of being passed on to the computer until the user leaves the monitor's on-screen menu.
