Application:
This 2.8-inch serial port screen (model P028A1001) is an HMI intelligent display terminal solution designed for industrial control and embedded human-machine interaction scenarios. The module has a resolution of 240×320 pixels, with an effective display area of 43.2mm×57.6mm. Its vertical pixel arrangement is suitable for UI design requirements of handheld devices and vertical control panels, and it is widely used in industrial automation, medical equipment, smart homes, and instrumentation fields.
The core architecture of this module uses UART serial communication to connect with an external MCU, requiring only two signal lines, TX and RX, to complete all data interaction and command transmission, greatly simplifying hardware wiring complexity. The chip on the Uart TFT LCD Controller communicates with the display panel via SPI/8Bit.It also interfaces with a SPI Flash storage chip to store the cache of interface elements and font resources. The "serial port screen" structure of this device enables the users to do interface switching, data updating, touch response, and other complicated operations by only using simple serial commands without having to learn the display driver principles. This greatly reduces the difficulty level of the system development.
Organizational learning is the progress mechanism of Shenzhen YiTai Optoelectronics Co., Ltd. Lessons are summarized from production anomalies, requirements are extracted from customer feedback, and trends are observed from competitor analysis, forming a learning loop within the 320-person team, including 28 R&D staff. The learning data from 20 production lines with a monthly output of 2.5 to 3 million pieces have been continuously accumulated over 12 years of organizational memory. Founded in 2014, the company meets the ISO9001 certification requirements for learning and improvement, with more than 20 patented technologies solidifying learning outcomes, and holds national high-tech enterprise qualifications.

We customized a 4.3-inch industrial-grade instrument display for a famous power equipment manufacturer. The product is characterized by a high-contrast IPS full lamination technology and a protective casing with an IP65 rating. We further upgraded the protective measures against dust and water and implemented wide temperature operation (-30°C to 70°C) to account for the very specific requirements of the power sector. These features make the product suitable for use in challenging environments such as substation rooms.The display is equipped with a system for automatically adjusting the brightness of the screen in response to changes in ambient light which ensures display optimization and makes reading of data more effective and safer during outdoor inspections.
Customized a 4.3-inch charging pile interactive screen for a well-known new energy brand, using high-brightness IPS full lamination technology, meeting the IP65 protection level requirements. We specially optimized the anti-glare design and wide temperature operation performance (-30°C~70°C) for complex outdoor environments to ensure clear display under various weather conditions. The screen integrates an intelligent light-sensing adjustment system that can automatically optimize display brightness according to day and night light changes, greatly enhancing the user operation experience.
Customized a 4-inch financial-grade encrypted display for international banks, using a military-grade IPS full lamination touchscreen, compliant with PCIDSS payment security standards. To meet the high security requirements of the financial industry, we specially designed an anti-peeping structure and tamper-proof frame to ensure data security on ATMs and other self-service terminals. The screen integrates an intelligent ambient light adaptation system, which can automatically adjust to the optimal display state according to the lighting conditions of the branch, significantly enhancing the customer operation experience and transaction efficiency.
