Display Transparency Data Transmission via Layer Superposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting layer transparency information or data of a transparency layer between chips require additional hardware interfaces, leading to significant power loss due to the need for separate channels for data transmission.
Innovation Solution
A data transmission method that acquires and processes data from both the display image layer and the transparency layer, constructs target layers for superimposed data, determines placement data for each layer, and transmits the resulting target layer data over a single channel, potentially compressing data if necessary to optimize power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate hardware interfaces (PCIe, USB, MIPI, Display Port) are deployed for transmitting transparency layer data, then data transmission capability is improved, but power consumption increases significantly
Solution Approach 1:
The patent merges the transparency layer data transmission with the existing display image layer data transmission by superimposing the transparency data onto the display data in the spatial domain. This combination allows both types of data to be transmitted through a single shared channel rather than requiring separate hardware interfaces, thereby reducing power consumption while maintaining transmission capability.
Solution Approach 2:
The patent makes the display data transmission channel universal by enabling it to carry both display image layer data and transparency layer data simultaneously. The channel is designed to handle multiple functions: transmitting display data, transparency data, and their superimposed combination, eliminating the need for dedicated separate channels for transparency data.
2Reliability
If additional hardware interfaces are deployed for transparency data transmission, then transmission channel capacity is improved, but hardware resource usage increases
Solution Approach 1:
The patent combines transparency layer data with display image layer data into a single superimposed data stream. This merging reduces hardware resource usage by eliminating the need for additional separate transmission channels, interfaces, and associated hardware components that would otherwise be required for independent transparency data transmission.
Solution Approach 2:
The existing display data transmission channel is made multi-functional to handle both display data and transparency data. This universality reduces hardware complexity by reusing existing infrastructure rather than adding new dedicated hardware resources for transparency data transmission.
3Reliability
If separate channels are used for display data and transparency data, then data independence is improved, but data synchronization becomes more difficult
Solution Approach 1:
The patent merges transparency data and display data into a single superimposed data stream that is transmitted through one channel. This ensures that both data types arrive simultaneously at the receiving end, maintaining perfect synchronization while preserving data independence through the superimposition technique that allows selective extraction and processing of each layer.

AI summary
A data transmission method includes: acquiring data of a display image layer and data of a transparency layer and determining, based on the data of the display image layer and the data of the transparency layer, multiple sets of data to be superimposed; constructing a target layer based on the display image layer and the transparency layer for each set of data to be superimposed; determining first placement data and second placement data of the corresponding target layer based on the data of the display image layer and the data of the transparency layer for each set of data to be superimposed; placing the first placement data to a first position of the corresponding target layer and placing the second placement data to a second position of the corresponding target layer, to obtain data of the corresponding target layer; and transmitting data of multiple target layers.
