General Description
The LSR043T04-R-V1 is the original specification for this 4.3-inch module family. Its content structure and core parameters are very similar to the V2 version. The specification provides all essential information for integration: a full pinout, electrical requirements, detailed RGB timing, and optical performance. The power sequence information is crucial for reliable initialization and preventing damage.
Comparison with LSR043T04-R-V2
The specifications between V1 and V2 appear largely identical in the provided fragments. Differences, if any, would typically be found in minor electrical tolerances, optical performance improvements (e.g., V2 lists 500 cd/m² luminance vs. V1's 380 cd/m²), or updated mechanical tolerances. The V2 likely represents a minor revision or optimization of the original V1 design.
Conclusion
The LESSON Smart Display LSR043T04-R-V1 is a thoroughly documented and proven display module. Its detailed specifications provide engineers with everything needed to successfully integrate this widely adopted 4.3-inch wide-screen display into their products, forming the basis for its successor versions.
