Core Viewpoint - LG Display has commenced mass production of fourth-generation OLED panels for 27-inch displays, achieving a peak brightness of 1500 nits and a refresh rate of up to 280Hz [1][2]. Group 1: Product Features - The new panels utilize Primary RGB Tandem technology, stacking red, green, and blue colors into four independent layers, allowing for a peak brightness of 1500 nits based on an average picture level (APL) of 1.5% [2]. - These panels can achieve 99.5% color accuracy and a response time of 0.03 milliseconds, significantly faster than traditional LCD displays, which typically have a response time of 1.0 milliseconds [3]. - LG Display has also developed a QHD resolution OLED display panel with a refresh rate of 540Hz, with mass production expected to start in the second half of the year after product evaluations by global manufacturers [4]. Group 2: Technical Innovations - The company faces challenges in maintaining picture quality for screens with refresh rates exceeding 500Hz, which it addresses through the development of new algorithms [5]. - LG Display's dynamic frequency and resolution technology allows for a maximum refresh rate of 720Hz at high definition, enabling users to select appropriate refresh rate modes based on specific content [6]. - The panels are designed with special films and improved board structures to block 99% of internal and external light reflections, ensuring that picture quality remains unaffected under 500 lux lighting conditions [7].
