Abstract

The present disclosure provides a frame with adjustable flatness, comprising: a rectangular frame composed of two pairs of opposite frame bars; a plurality of upper ribs, any one of the plurality of upper ribs spans the rectangle after being stretched The two ends of the frame are respectively connected to the upper surfaces of the two opposite frame bars; and a groove is formed at the bottom of the rectangular frame, and the extension direction of the part of the groove in any frame bar is consistent with the extension direction of the frame bar; Wherein the groove is provided with at least one lower rib, the extension direction of the lower rib is consistent with the extension direction of the frame bar where the lower rib is located, and the two ends of the lower rib are stretched and aligned with the lower surface of the rectangular frame connect. By designing grooves at the bottom of the frame and stretching the pre-connected lower ribs in the grooves, the tension through these lower ribs causes the frame to bend downward enough to offset the amount of upward bending caused by the upper ribs, so that the The flatness of the frame needs to be adjusted.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a frame with adjustable flatness. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) is a display lighting technology that has gradually developed in recent years, especially in the display industry. It is one of the hotspots in the field of flat panel display research. , high contrast, flexibility, low energy consumption, low production cost, self-illumination, wide viewing angle and fast response, etc. At present, OLEDs have begun to replace traditional LCD displays in the display fields of mobile phones, PDAs, and digital cameras. It is considered to have broad application prospects and has important research significance. In particular, top-emitting OLED devices have become the main direction of research due to their higher aperture ratio and the use of microcavity effects to optimize light extraction. Unlike TFT-LCD, ...
