Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the active display panel is used to improve image contrast in low ambient light, then image contrast is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches between transflective and active display modes based on ambient light conditions detected by the sensing module. The local controlling module adjusts the operating state of each panel in real-time, enabling the display to adapt to changing environmental conditions and optimize the balance between image contrast and power consumption
Solution Approach 2:
The system changes the operational parameters of the display panels by switching between different display modes (transflective mode for high ambient light, active mode for low ambient light). The local controlling module adjusts luminous intensity parameters to maintain optimal image quality while managing power consumption across different operating conditions
2Use of energy by moving object
If the transflective display panel is used to save power in high ambient light, then power consumption is reduced, but color accuracy deteriorates due to color shift
Solution Approach 1:
The sensing module provides feedback about ambient light conditions to the local controlling module, which then adjusts the display mode accordingly. This feedback mechanism ensures that the transflective panel is used only when ambient light conditions are sufficient to maintain acceptable color accuracy, while still achieving power savings
Solution Approach 2:
The system dynamically adjusts between transflective and active display modes based on real-time ambient light detection. This dynamic switching allows the system to use the power-efficient transflective mode when color accuracy requirements are met by sufficient ambient light, while switching to active mode when color accuracy would deteriorate
3Use of energy by moving object
If the transflective display panel allows ambient light penetration to form a new display, then power is saved, but control accuracy deteriorates due to difficulty in switching between panels
Solution Approach 1:
The local controlling module pre-processes the ambient light information from the sensing module and proactively determines the optimal display mode before switching is needed. This preliminary processing enables accurate and timely switching decisions between transflective and active panels based on environmental conditions
Solution Approach 2:
The local controlling module acts as an intermediary between the sensing module and the display panels, processing environmental information and generating appropriate control signals. This intermediary function ensures accurate interpretation of ambient light conditions and precise control of panel switching and luminous intensity adjustment

AI summary
A composite display controlling system is proposed, and includes a composite display device, a sensing module and a local controlling module. The composite display device includes a transflective display panel and an active display panel. The sensing module senses the environment surrounding the composite display device to generate environmental information. The local controlling module is connected to the composite display device and the sensing module, and compares the environmental information with an environmental judgment data to generate an environmental comparison result. The local controlling module generates a first control signal and a second control signal according to the environment comparison result, and controls the opening and closing of the trans-reflective display panel and the active display panel. The local controlling module adjusts the second control signal according to a transmission spectrum of the transflective display panel to calibrate the luminous intensity of the active display panel.
