The three controllers △MXT112UD-MAUHA1, △MXT228UD-MAUHA1, △MXT336UD-MAUHA1 meet various screen demands from 2 inches to 8 inches.
Microchip's unique safety features allow for system shutdown via the touchscreen soft button, eliminating the need for a separate MCU for an external safety certified stop or cancel button.
Additionally, various self-diagnosis functions enable the appliance to detect product malfunctions and automatically turn off the power.
High signal-to-noise ratio (SNR) design and microphoneBased on Lochip's differential mutual acquisition system, three new products enable touchscreens to detect and track multiple fingers even when the user is wearing gloves.

The Problem with AI is Not Performance, but Trust
CEO Kang Min-seung emphasized at Snowflake's World Tour Seoul that generative AI has entered a phase where "trust" rather than accuracy becomes the key competitive advantage. As AI is applied to various tasks including consultation, risk management, and operational automation, incorrect data, erroneous responses, and bias are creating actual business risks. He pointed out that enterprises must build a trust layer above AI. To achieve this, accurate data management, semantic structuring, governance, and prompt security are essential. He explained that AI is not merely an automation tool but a technology that reorganizes the entire organization's workflows and decision-making systems. Snowflake provides a platform that supports this trust-based AI operation, emphasizing that enterprises should build "trustworthy AI" rather than "intelligent AI."

The Decisive Factor for AI Agents in Finance: "Trustworthy Data Infrastructure"
The key to spreading AI agents in the financial sector is establishing a trustworthy data system. KB Kookmin Bank is operating over 100 AI agents by 2025 and is promoting expansion to 300. AI is automating repetitive tasks across various areas such as consultation, risk management, wealth management, and relationship management. However, if data quality, governance, and semantic structuring are insufficient, errors and risks increase. KB is building an AI-Ready organization through a multi-model strategy of GPT, Gemini, and Claude, as well as a Snowflake-based data system. The bank emphasized that AI has entered a phase where it restructures not just simple automation but the entire work process and decision-making system.
