Plane-curved-surface variable OLED screen and notebook computer

Abstract

The invention provides a plane-curved-surface variable OLED screen and a notebook computer. The plane-curved-surface variable OLED screen comprises a bearing steel plate, an OLED display assembly, a silica gel assembly, an inflation and deflation assembly and an opening and closing rotating shaft. The bearing steel plate can be bent and deformed after being pressed; the OLED display assembly is arranged on a front panel of the bearing steel plate in an attached mode, and the OLED display assembly deforms along with deformation of the bearing steel plate; the silica gel assembly is arranged ona rear panel of the bearing steel plate, and a plurality of closed cavities are formed in the silica gel assembly; the inflating and deflating assembly is communicated with the closed cavity and is used for controlling the internal air pressure of the closed cavity; and the bearing steel plate is arranged on the opening and closing rotating shaft. Through cooperation of the bearing steel plate, the OLED display assembly, the silica gel assembly, the inflation and deflation assembly, the opening and closing rotating shaft and other structures, a curved screen can be arranged on a notebook computer with a small size, and conversion of the screen between a curved surface and a plane can be achieved.

Description

technical field [0001] The invention relates to the technical field of OLED display equipment, and relates to a plane-curve variable OLED screen, in particular to a notebook computer with a plane-curve variable OLED screen. Background technique [0002] OLED, Organic Light-Emitting Diode, also known as organic electric laser display, is a phenomenon of luminescence caused by carrier injection and recombination, and its luminous intensity is proportional to the injected current. Under the action of an electric field in an OLED, the holes generated by the anode and the electrons generated by the cathode will move, inject into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy will be generated. Excitons, which excite light-emitting molecules eventually produce visible light. OLED display devices have the advantages of being thinner, lighter and more flexible, an...

Problems solved by technology

[0004] In the prior art, large-size curved screens generally use the curved back shell as the focus to realize the bending of the panel, or use a thick back shell to wrap the mechanical structure of the plane-curved surface transformation of the control panel. Limited by this, large-size Curved screens can usually only be used on TVs or desktop monitors, while notebooks cannot be equipped with curved screens, let alone convert between curved and flat screens
