Programmable Serializer for Video Display Resolution Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing serializers for video data in cellular phones are limited by their fixed serialization ratio, which restricts the resolution of displays and requires different serializers for varying display resolutions, increasing complexity and cost.
Innovation Solution
A programmable serializer with an input circuit and data parsers that receive parallel data and a mode select signal, allowing for dynamic configuration of serial output channels to match the display resolution, enabling flexible output in one, two, or three serial channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed serialization ratio serializer is used, then the serializer structure is simple, but the display resolution is limited and cannot be adjusted
Solution Approach 1:
The serializer employs a programmable data parser that can dynamically reconfigure the number of output data streams based on control signals. The data parser includes multiple multiplexers and shift registers that can be programmed to operate in different modes (e.g., 1-output mode, 2-output mode, 3-output mode), allowing the serialization ratio to be adjusted according to the display resolution requirements without changing the physical serializer structure.
Solution Approach 2:
The invention changes the operational parameters of the serializer by introducing mode select signals that control the data parser to operate at different serialization ratios. By changing the control parameters (mode select signals) rather than the physical structure, the serializer can adapt to different display resolutions. The data parser reconfigures its internal connections and output channels based on these parameter changes.
2Adaptability or versatility
If different serializers are used for different display resolutions, then the display resolution compatibility is improved, but the number of signal conductors through the hinge increases
Solution Approach 1:
The serializer is designed as a universal device that can serve multiple display resolution requirements through a single unit. The programmable data parser can be configured to generate different numbers of output data streams (1, 2, or 3 channels) depending on the display resolution needed. This multi-functionality eliminates the need for multiple dedicated serializers for different resolutions, thereby reducing the number of signal conductors required through the hinge assembly.
Solution Approach 2:
The serializer dynamically adapts its output configuration based on the required display resolution. By using control signals to reconfigure the data parser's operation mode, the same physical serializer can provide different numbers of output channels as needed, making the system flexible and reducing the need for multiple fixed-configuration serializers and their associated conductors.
3Productivity
If the output data rate of the serializer is fixed, then the serializer design is simplified, but it cannot match the consumption rate of displays with different resolutions
Solution Approach 1:
The serializer incorporates a programmable data parser that can dynamically adjust the number of output data streams based on control signals. This allows the output data rate to be matched to the consumption rate of displays with different resolutions. The data parser reconfigures its internal logic and output channels to provide the appropriate data rate without requiring multiple fixed-rate serializers.
Data Source
AI summary
A serializer receives parallel data and a control signal. The serializer splits the parallel data into multiple subportions of data and, based on the control signal, sequentially outputs each of said subportions as serial output data in one or more serial output channels. The number of serial output channels is dictated by the control signal.
