Market Research: In recent years, AI has become the latest "traffic password" across various industries, and the toy industry is no exception. Many companies have made layouts in the field of AI-companion toys, including not only traditional toy manufacturers (such as Aofei Entertainment and Shifeng Culture) but also technology companies (ByteDance, Tesla, FoloToy, etc.). They have their own advantages in product development, IP accumulation, and self-developed large models, and have successively launched new products. According to data released by the Joint Research Industry Research Institute, the global AI toy market is expected to grow from approximately $8.7 billion in 2022 to $35.11 billion in 2030, with a compound annual growth rate of over 16%. Therefore, this project is worth designing and developing, and efforts should be made to meet customer requirements.
Project initiation: Based on the customer's product requirements, we have selected a cost-effective and mature industrial-grade round 1.28-inch LCD+IC combination solution for project initiation. The LCD features a resolution of 240*240, with a pixel density of 188PPI for high clarity, IPS full viewing angle, and a module brightness of 300cd/m², meeting the brightness requirements of the product usage scenarios.
Structural Design: Design the overall structure of the display module to ensure tight coordination and reliable fixation of components such as the display screen, backlight, and FPC. Taking into account the product's thin and lightweight requirements, lightweight materials and a compact structural design are adopted, while meeting performance requirements such as heat dissipation, shock resistance, and protection.
Electronic design: The new project's display module interface is designed to be compatible with SPI, SPI+RGB, QSPI, and MCU interfaces, providing compatibility and convenience for selecting different drive modes for subsequent platform solutions. The schematic and specification sheet (including detailed electrical and timing specifications) are shown below:

Optical performance testing: After the production of the display module sample, the professional optical testing equipment BM-7 is used to test and evaluate the optical performance indicators such as brightness, color, contrast, and viewing angle of the display module, ensuring that all indicators meet the design requirements.
Electrical performance testing: Conduct electrical performance testing on the driver circuit, interface circuit, etc. of the display module, including signal integrity testing, power consumption testing, etc. The stability and reliability of the circuit meet the design requirements.
Environmental reliability testing: Place the display module in a reliable experimental environment with industrial control specifications such as high temperature, low temperature, high humidity, etc., simulate various working conditions in actual use, and ensure that the product's environmental adaptability and reliability meet the design specifications.
Preparation for mass production: After completing testing and validation, preparations are made before mass production, including optimization of production processes, debugging of production equipment, completion of drawing upload systems, procurement and delivery of raw materials, and quality control, ensuring the smooth progress of the mass production process and consistency of product quality.
