[0004] Among them, AMOLED (Active-matrix organic light emitting diode, active matrix organic light-emitting diode) has the characteristics of high resolution, wide viewing angle, fast response, self-illumination, etc., and is widely used. Due to the glare effect, most OLED products currently choose a combination of λ / 4 polarizer and linear polarizer to eliminate the influence of external natural light on AMOLED. Although this can avoid the influence of external natural light on AMOLED, it also leads to organic electroluminescence. Nearly 50% of the self-luminescence of the device is lost

The invention provides an optical thin film. The optical thin film comprises a transparent thin film body, wherein a plurality of grooves are formed in a surface of one side of the thin film body, andbulges are formed between adjacent grooves. The invention also provides an organic light emitting diode display panel. The organic light emitting diode display panel comprises an organic light emitting diode device and a package layer and also comprises the optical thin film, wherein the package layer is arranged on the organic light emitting diode device, the optical thin film is arranged on a surface of one side, deviating from the organic light emitting diode device, of the package layer, and the grooves are opposite to light emitting regions of the organic light emitting diode devices. The invention also provides a fabrication method of the organic light emitting diode display panel. Compared with the prior art, the optical thin film has the advantages that the grooves are formed in the thin film body, an existing polarization plate is substituted by the optical thin film, natural light irradiates the grooves and then are annihilated by reflection for many times to cause light loss, so that the loss of automatic lighting light of the organic light emitting diode device is reduced as well as the influence of the natural light on the organic light emitting diode device is reduced, and moreover, and the production cost is also reduced.
Description
technical field [0001] The invention relates to a liquid crystal display panel technology, in particular to an optical thin film, an organic electroluminescence display panel and a manufacturing method thereof. Background technique [0002] With the development of information technology and mobile communication technology, display devices capable of displaying visual images have also been developed. Flat panel display devices such as liquid crystal display (LCD) devices and organic light emitting display (OLED) devices are developed and used. [0003] In general, an LCD device includes a liquid crystal panel including an upper substrate (color filter (CF) substrate) and a lower substrate (thin film transistor array (TFT) substrate) and a liquid crystal layer ( LC). The liquid crystal layer is driven by an electric field generated between the pixel electrode and the common electrode to display images. An OLED device includes an organic light emitting diode including an ano...
