Engineering Contradiction Analysis
1Use of energy by moving object
If a liquid crystal display is used, then power consumption is reduced and viewing angles are improved, but response time becomes excessively long (50 to 100 times longer than CRT displays)
Solution Approach 1:
A transfer electrode is introduced as an intermediary between the pixel electrode and the common electrode. This transfer electrode receives charge from the common electrode and transfers it to the pixel electrode, enabling faster charging of the liquid crystal molecules without requiring higher overall power consumption, thus improving response time while maintaining low power consumption characteristics
Solution Approach 2:
The display system dynamically switches between different driving modes: a first driving method using the transfer electrode for fast response during transitions, and a second driving method without the transfer electrode for normal operation. This dynamic adaptation allows the system to achieve fast response times when needed while maintaining the low power consumption benefits of liquid crystal technology during steady-state operation
2Speed
If response time is reduced by conventional means, then speed improves, but power consumption increases and the advantage of liquid crystal displays is lost
Solution Approach 1:
The electrode structure is segmented into three parts: pixel electrode, common electrode, and transfer electrode. This segmentation allows the transfer electrode to handle the high-current transient charging operation separately from the pixel electrode, enabling fast response without requiring the entire display system to operate at higher power levels continuously
Solution Approach 2:
The transfer electrode is pre-charged from the common electrode before the actual pixel switching occurs. This preliminary charging action prepares the transfer electrode to rapidly discharge to the pixel electrode, achieving fast response times without requiring excessive power during the pixel operation itself, thus maintaining low overall power consumption

Disclosed are a form converting mechanism and a display apparatus. A first connecting member (11) in the form converting mechanism includes a first outer end (111), a first pivotal portion (112) and a first inner end (113). A second connecting member (12) includes a second outer end (121), a second pivotal portion (122) and a second inner end (123). Two ends of the third connecting member (13) are respectively pivoted with the first pivotal portion (112) and the second pivotal portion (122), and two ends of the fourth connecting member (14) are respectively connected to the first inner end (113) and the second inner end (123). After at least one of the first connecting member (11), the second connecting member (12), the third connecting member (13), and the fourth connecting member (14) that has constituted the linkage mechanism bears an external force, the third connecting member (13) is cooperated with the fourth connecting member (14), so that the distance between the first outer end (111) and the second outer end (121) changes steadily, and the form of the flexible screen body (2) connected to the first outer end (111) and the second outer end (121) changes stably under the action of the first outer end (111) and the second outer end (121), which improves the form stability of the flexible screen body (2) after the form converting, and improves the quality of the form converting of the flexible screen body (2).
