Pacific Crest Securities has highlighted several companies that might benefit from Apple’s decision to use OLED displays in next year’s iPhones, according to a report from Investor Business Daily.

The companies listed by the investment company included Applied Materials (AMAT), Advanced Energy Industries (AEIS) and MKS Instruments (MKSI).

Based on Pacific Crest analyst Weston Twigg’s analyses, OLED adoption is “a positive trend” for Apple, Applied Materials, Advanced Energy Industries and MKS Instruments, while touch-interface supplier Synaptics (SYNA) outlook is uncertain. The touch controller could be replaced when smartphone makers swap LCD displays with OLEDs.

Semiconductor equipment maker Applied Materials announced last week, display orders in second quarter skyrocketed 483%, driven by demands for machines used to manufacture OLED displays.

Applied Materials stock was up 23% after it reported its second quarter earnings after the market closed on May 19, 2016. The company’s stock climbed up 3% to US$ 24.44 on the stock market, the highest level in more than a year.

Chip makers Advanced Energy Industries and MKS Instruments also climbed up 2% to US$ 37.86 and 2.3% to US$ 40.95 respectively, reaching its highest peak since May 2002.

Universal Display has also benefitted from the announcement, as a key supplier of technology and materials for OLED displays. The company’s stock dropped slightly from its all-time high of 68.17 to 67.78.

Samsung will add one new OLED Gen. 6.5 production line to its three production lines by late next year, said Twigg.
