HDMI Display Control via Smart Device for Button-Free Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display device adjustment methods, such as adjusting brightness, contrast, and volume, require numerous physical button presses, making them cumbersome and time-consuming.
Innovation Solution
A display control system utilizing a smart device connected via HDMI and DDC, which receives commands from a remote control device to adjust display parameters, including brightness, contrast, and volume, using the VESA MCCS standard, thereby simplifying the adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical buttons are used to adjust display parameters, then the display device can be controlled, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent introduces a smart device as an intermediary between the user and the display device. The smart device receives control commands from a remote control device and transmits display control commands to the display device through HDMI and DDC interfaces, eliminating the need for users to directly operate physical buttons on the display device.
Solution Approach 2:
The patent replaces the mechanical button-pressing system with an electronic command transmission system. Instead of physically pressing buttons on the display device, users send commands via a remote control device to the smart device, which then transmits electronic control commands through HDMI and DDC interfaces to adjust display parameters.
2Ease of operation
If physical buttons are disposed on the display device frame, then direct control is possible, but the device complexity increases
Solution Approach 1:
The patent extracts the control functionality from the display device itself and relocates it to a smart device. The display device no longer requires physical buttons or complex control circuits on its frame, as all control operations are performed externally through the smart device that interfaces with the display via HDMI and DDC.
3Measurement precision
If manual button pressing is required for each parameter adjustment, then precise control is achieved, but productivity decreases
Solution Approach 1:
The patent implements preliminary action by having the smart device pre-process control commands from the remote control device and convert them into standardized display control commands compliant with VESA MCCS standards. This preparation work is done in advance before the commands are transmitted to the display device, streamlining the adjustment process.

AI summary
A display control system includes a remote control device and a smart device. The remote control device transmits a control command. The smart device is paired with the remote control device to receive the control command. The smart device transmits a display control command to a display device according to the control command, thereby adjusting a display parameter of the display device. The smart device is connected to the display device through a high definition multimedia interface (HDMI). The smart device transmits the display control command to the display device through the HDMI and a Display Data Channel (DDC) and in compliance with a Video Electronics Standards Association (VESA) Monitor Control Command Set (MCCS) standard.
