16 Years of Focus, Profound Technical Accumulation

Founded in 2008, we have been consistently focusing on the R&D and manufacturing of TFT-LCD technology. 16 years of continuous investment have enabled us to accumulate full-cycle core technical expertise spanning panel selection, circuit design, backlight optimization and reliability verification. This comprehensive, professional specification sheet you are reading is a testament to our profound industry experience.

"Hidden Champion" Quality Philosophy

As a small-to-medium-sized manufacturer, we are fully aware that we cannot compete on scale. Therefore, we have chosen ultimate reliability as the cornerstone of our business. We treat every display panel with the same meticulousness as we would a precision instrument. From the rigorous supplier selection for core ICs such as ST7796U, to the precise control of every process parameter on the production line, and even the 72-hour burn-in test before delivery, we implement internal control procedures that are more stringent than the universal industry standards.

Flexible and Efficient Customer Responsiveness

Unlike large-scale standardized factories, we boast the unique advantage of rapid response and flexible customization. Whether it is adjusting initialization code, optimizing backlight power consumption for you, or assisting in resolving compatibility issues with specific motherboards, our engineering team can provide more direct and personalized professional technical support to overcome project challenges together with you.

Transparency and Integrity: The Cornerstone of Cooperation

We firmly believe that long-term cooperation begins with transparency. Every parameter (including minimum and typical values) specified in this document is derived from actual tests conducted in our own laboratories, with absolutely no exaggeration. We are happy to share technical details on topics such as wide-temperature operational stability and ESD protection design, because over 16 years, we have translated these experiences into product capabilities that you can trust.
