Samsung Display Corporation (SDC; wholly owned by Samsung Electronics; ~KRW 30T revenue) is South Korea's second-largest display maker; primarily focused on smartphone OLED but growing into laptop OLED; ~8% laptop display market share (2024, growing). SDC's Asan A3 fab (Chungnam Province) is the primary OLED production site for premium laptops — Samsung MacBook Pro (Apple's primary OLED supplier), Dell XPS 13 OLED, Asus ProArt OLED. SDC is Apple's largest OLED MacBook Pro panel supplier for the 2024-2026 generation. SDC's laptop OLED share growing rapidly as Apple expands OLED MacBook lineup (14" in 2026). SDC does not make laptop LCD panels at meaningful scale — it exited mainstream LCD early.

LG Display Co. Ltd. (KRX: 034220; ~KRW 26T revenue; 37.9% owned by LG Electronics, 7.4% by LG Corp) is South Korea's largest display maker; ~15% laptop display market share, predominantly premium OLED and IPS LCD. LG Display's Paju Korea complex (P8, P9, P10 fabs) produces both IPS LCD and OLED panels — Paju is the world's largest OLED panel production site. LGD is executing an explicit strategic retreat from LCD toward OLED: its Guangzhou China Gen 8.5 LCD fab (capacity 90,000+ sheets/month) is being closed or sold as Chinese makers commoditized the LCD market. LGD supplies OLED panels for the Apple MacBook Pro 14"/16" (launched 2024) and Dell XPS OLED. The pivot to OLED is existential — LGD cannot compete with BOE on LCD price; OLED premium is its survival path.

BOE Technology Group Co. (SZSE: 000725; ~¥200B revenue; state-owned enterprise ultimately controlled by Beijing municipal government through BOEAG) is China's national champion display maker and world's largest laptop LCD panel supplier; ~20%+ and growing share of global laptop panels. BOE received an estimated $60B+ in cumulative state subsidies (grants, subsidized land, below-market loans from policy banks) from 2003-2024 — by far the largest state-sponsored industrial buildout in display manufacturing history. Key fabs: Beijing B7 (Gen 8.5), Chengdu B7+ (Gen 8.6+), Wuhan B10 (Gen 10.5), Chongqing B10+ (Gen 10.5+), Fuzhou B18 (Gen 8.6 OLED). BOE is the first Chinese company to qualify as a supplier for Apple MacBook Pro OLED panels (starting 2024 qualification; production ramp 2025-2026 — though Samsung Display and LG Display remain Apple's primary OLED sources). BOE's aggressive expansion drove LG Display and AUO out of mainstream LCD into OLED/specialty.
