Problems solved by technology

[0011] However, for the organic electroluminescent display panel 100, as the current signal between the counter electrode 15 and the lower electrode 11 increases, and the instantaneous brightness of the organic light emitting layer 13 increases, the material structure of the organic light emitting layer 13 will damage
Therefore, for the organic electroluminescent display panel 100, especially when the organic electroluminescent display panel 100 is a passive organic electroluminescent display panel (PassiveMatrix OLED), as the number of counter electrodes 15 increases, there will be The service life of the electromechanical excitation light-emitting display panel 100 has a great influence

Embodiment Construction

[0040] First, see image 3 and Figure 4 Shown are a top view and a schematic cross-sectional view of a partial structure of a preferred embodiment of an organic electroluminescent display panel with improved service life of the present invention. As shown in the figure, the organic electroluminescent display panel 300 of the present invention is mainly provided with at least one organic electroluminescent component 30 on a color filter 40. The color filter 40 is provided with at least one color photoresist 45 and a black matrix 43 on a transparent substrate 41, and then a planarization layer is sequentially provided on the black matrix 43 and / or the color photoresist 45 (overcoat) 47 and / or barrier layer (barrier layer) 49.

[0041] The organic electroluminescence component 30 can be a passive matrix OLED, including a stack of at least a bottom electrode 31, an organic light-emitting layer 33, and a counter electrode 35, wherein the bottom electrode 31 and the counter electrode 3...

Abstract

The invention discloses an organic electroluminescence display panel, especially an organic electroluminescence display panel able to prolong service life, mainly making corresponding regulation on the number of bottom electrodes and aligning electrodes of a traditional electroluminescence display panel and making the number of configured aligning electrodes less than that of configured bottom electrodes, thus able to reduce the supplied instantaneous currents between the bottom electrodes and aligning electrodes and the instantaneous brightness of organic luminous layers on the premise of not influencing display brightness of the display panel, so as to prolong the service life of the display panel.

Description

Technical field [0001] The present invention relates to an organic electroluminescent display panel with improved service life, in which the number of lower electrodes and counter electrodes is changed to achieve the purpose of reducing the instantaneous brightness of an organic light-emitting layer. Background technique [0002] With the continuous improvement of manufacturing technology in the electronics industry, some portable electronic products have also prospered, such as mobile phones, PDAs and pen-based computers. The display screens used in these portable electronic products mainly include liquid crystal displays (LCD), plasma displays (PDP) and organic electroluminescent devices (OLED). [0003] Among them, compared with other display technologies, organic electroluminescent display devices have the advantages of self-luminescence, high brightness, wide viewing angle, low power consumption, high response speed, light and thin panel, simple component structure and simpl...
