XIV . Segment reporting
1 Segment reporting considerations
The Group management reviews the operation performance and allocates resources according to the business segments below.
(a) Display business —The display business integrates design and manufacturing of display devices and strives to offer TFT-LCD, AMOLED, Microdisplay and other intelligent interface devices. This business focuses on providing high-quality
smartphones, tablet PCs, laptops, monitors, TVs, vehicles, electronic shelf label (ESL), industrial control, domiciliary medical applications, wearable devices, interactive
whiteboards , splice displays, business devices, VR/AR devices and other display devices for customers.
(b) IInternet of Things (IoT) innovation business —The IoT innovation business integrates manufacturing models for system solution design, providing customers with competitive smart terminal products in the fields of TVs, monitors, laptops, tablet PCs, low power consumption products, IoT, 3D displays, etc. With artificial intelligence and big data as technical support, it focuses on products and services that integrate software and
hardware, providing integrated solutions in IoT segments such as smart finance, smart industrial parks, visual arts, smart administration, smart transportation etc.
(c) Sensor business —The sensor and application solutions integrate manufacturing models for system solution design. It focuses on various fields such as medical bio- detection, transportation and construction intelligence visions, consumer electronics, microwave communication and industrial sensing, providing customers with integrated design and manufacturing of sensor devices and system solution services. Specific products and solutions include flat panel X-ray detectors (FPXD), digital microfluidic chips, PDLC glass, fingerprint identification systems, industrial sensors, etc.
(d) MLED business —The MLED integrates design and manufacturing of devices and provides Mini-LED backlight products with strong reliability and high dynamic range that allow precisely brightness adjustment for smartphones, tablet PCs, laptops, monitors, TVs, car displays, wearables and other products; besides, it provides
Mini/Micro-LED display products with high brightness, strong reliability and high contrast for the usage of outdoor display, commercial display, transparent display, special display and other scenarios.
(e) Smart medicine and engineering business —The smart medicine and engineering provides professional healthcare services and features the innovative integration of medical and engineering by integrating engineering technology and medical science. Adhering to people-centred thought, this business focuses on family, community and
hospital, connecting testing equipment, medical personnel and costumers by health IoT platform, constructing intelligent health administrative ecosystem, providing customers with a "prevision-treatment-nursing" full-chained health services.
(f) Others —Other service mainly includes technical development service and patent maintenance service.
The main reason to separate the segments is that the Group independently manages the display business, IoT innovation business, sensor and application solutions, MLED and smart medicine and engineering and other businesses. As these business
segments manufacture and sale different products, apply different manufacturing processes and specifies in gross profit, the business segments are managed
independently. The management evaluates the performance and allocates resources according to the profit of each business segment and does not take financing cost and investment income into account.
2 Accounting policies for the measurements of reporting segments
For the purposes of assessing segment performance, the Group’s management regularly reviews the revenue and costs attributable to each reportable segment. Inter-segment sales are determined with reference to prices charged to external parties for similar orders.
