Problems solved by technology
[0004] However, due to the existence of various metal layers in the display panel, in the absence of polarizers, in the area corresponding to the camera under the display panel, the external light will be specularly reflected on the metal layer, and these reflections will cause the display When the panel is in the off-screen state, there is a problem of inconsistent brightness between the area corresponding to the camera and the display area, which seriously affects the imaging effect of the screen

The invention provides a display panel and a mobile terminal.The display panel comprises a display sub-area and a light-transmitting function display sub-area adjacent to the display sub-area, and the display panel comprises a display panel body and a color filter layer arranged on the light-emitting side of the display panel body; the display panel body comprises a first metal layer and an organic light-emitting layer which are arranged in a stacked mode, the first metal layer comprises a plurality of first electrodes which are located in the light-transmitting function display subarea and arranged at intervals, each first electrode comprises an overlapping part and an exposed part, and the display panel comprises a shielding part; according to the display panel, the shielding part is used for shielding the exposed part of the first electrode, so that most of light enters the first electrode to be reflected and then can be shielded by the shielding part, the reflectivity of the display panel in the light-transmitting function sub-region is reduced, the brightness of the light-transmitting function display sub-region is close to or consistent with that of the display sub-region, and the display effect is improved. Therefore, the problem that the display brightness of the light-transmitting function display sub-area and the display sub-area in the existing display panel is inconsistent is solved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a mobile terminal. Background technique [0002] In the existing organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel, the polarizer can effectively reduce the reflectance of the panel under strong light, but loses nearly 58% of the emitted light. For the OLED display panel, this greatly increases the lifespan burden. [0003] At present, in the existing display panel, the above-mentioned problem can be solved by usually replacing the polarizer with a color filter layer (Color Filter, CF for short). The display panel using the color filter technology can not only realize the thinning of the display panel, but also increase the light output rate of the display panel from 42% to 60%, and improve the contrast of the display panel. [0004] However, due to the existence of various metal layers in the display panel, in the ab...
