背景技术Background technique
随着显示技术的蓬勃发展，高色域已经成为一个重要发展方向。高色域意味着显示画面具有更加丰富多彩的色彩，具有更强的色彩展现能力。QD（Quantum Dot，量子点）显示技术属于创新半导体纳米晶体技术，可以准确输送光线，高效提升显示屏的色域值以及视角，让色彩更加纯净鲜艳，使色彩表现更具张力。采用该技术的显示器不仅能产生色域范围更广的动态色彩，还能在画质中展现真实的色板，超越了传统意义上的背光技术。With the vigorous development of display technology, high color gamut has become an important development direction. High color gamut means that the display screen has more colorful colors and a stronger color display ability. QD (Quantum Dot, quantum dot) display technology is an innovative semiconductor nanocrystal technology that can accurately transport light, efficiently improve the color gamut value and viewing angle of the display, make colors more pure and bright, and make color performance more tense. Displays using this technology can not only produce dynamic colors with a wider color gamut, but also show real color palettes in image quality, surpassing the traditional backlight technology.
OLED(Organic Light Emitting Diode，有机发光二极管)显示技术的快速发展，推动曲面和柔性显示触控产品迅速进入市场，相关领域技术更新也是日新月异。OLED是指利用有机半导体材料和发光材料在电场驱动下，通过载流子注入和复合导致发光的二极管。OLED(Organic The rapid development of Light Emitting Diode (Organic Light Emitting Diode) display technology has promoted the rapid entry of curved and flexible display touch products into the market, and technology updates in related fields are also changing with each passing day. OLED refers to a diode that uses organic semiconductor materials and light-emitting materials to emit light through carrier injection and recombination driven by an electric field.
QD-OLED显示面板结合了OLED电致发光技术以及量子点QD光致发光技术，包括发射蓝光的OLED阵列基板、量子点光致转换膜以及彩色滤光片(Color Filter，简称CF)。QD-OLED显示面板利用蓝光OLED作为光源，激发量子点光致转换膜中红/绿量子点，红色量子点在接收到蓝光之后，会激发出红光通过彩色滤光片透出，绿色量子点在接收到蓝光之后，会激发出绿光通过彩色滤光片透出，蓝光会直接透过彩色滤光片，从而形成全彩显示。QD-OLED显示面板具有广色域，广视角等优异的性能，视为大尺寸OLED的潜在技术。The QD-OLED display panel combines OLED electroluminescence technology and quantum dot QD photoluminescence technology, including blue-emitting OLED array substrates, quantum dot photoconversion films, and color filters (Color Filter, referred to as CF). The QD-OLED display panel uses blue OLED as the light source to excite the red/green quantum dots in the quantum dot photoconversion film. After receiving the blue light, the red quantum dots will excite red light to pass through the color filter, and the green quantum dots After receiving the blue light, it will excite the green light to pass through the color filter, and the blue light will directly pass through the color filter to form a full-color display. QD-OLED display panels have excellent performance such as wide color gamut and wide viewing angle, which are regarded as potential technologies for large-size OLEDs.
技术问题technical problem
由于红/绿像素需要蓝光OLED通过激发量子点转换发射出红光/绿光，剩余的蓝光被彩色滤光片过滤掉，因此，红光/绿光亮度受限于量子点光转换水平。目前受限于蓝光效率较低，会影响显示面板整体亮度及降低显示面板寿命。Since the red/green pixel requires the blue OLED to emit red/green light by exciting the quantum dot conversion, and the remaining blue light is filtered by the color filter, the brightness of the red/green light is limited by the quantum dot light conversion level. Currently, it is limited by the low efficiency of blue light, which will affect the overall brightness of the display panel and reduce the life of the display panel.
