一种显示面板及显示装置
摘要：
本发明提供一种显示面板及显示装置，显示面板包括彩膜基板和阵列基板，彩膜基板和阵列基板之间设有发光单元，发光单元包括依次层叠设置的第一电极层、有机发光层和第二电极层，显示面板具有显示区域和透光区域，有机发光层朝向出光方向的一侧设有第一透过率调节层，有机发光层背离出光方向的一侧设有第二透过率调节层，且第一透过率调节层和第二透过率调节层均位于透光区域内，有机发光层发出的光线可激发第一透过率调节层和第二透过率调节层调节透光区域的光线透过率，第一透过率调节层和第二透过率调节层在该光线的激发下改变自身的光线透过率，从而对透光区域的光线透过率进行调节，可提高透光区域和显示区域的光对比度，提高显示质量。
摘要（英）：

The present invention provides a display panel and a display device, the display panel includes a color film substrate and an array substrate, a light emitting unit is arranged between the color filmsubstrate and the array substrate, the light emitting unit includes a first electrode layer, an organic light emitting layer and a second electrode layer arranged in a cascading manner in turn, the display panel has a display area and a light transmitting area, a first transmissivity adjusting layer is arranged on one side of the organic light emitting layer facing the direction of light emission,a second transmissivity adjusting layer is arranged on one side of the organic light emitting layer away from direction of light emission, and the first transmissivity adjusting layer and the secondtransmissivity adjusting layer locate in the light transmitting area, light rays emitted by the organic light emitting layer can activate the first transmissivity adjusting layer and the second transmissivity adjusting layer to adjust the light transmittance of the light transmitting area, and the first transmissivity adjusting layer and the second transmissivity adjusting layer are activated by the light rays to change their own light transmissivity so as to adjust the light transmissivity of the light transmitting area, thus the light contrast of the light transmitting area and the display area are improved to improve display quality.
