Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0046] For now, please refer to figure 1 , the electroluminescent display panel 100 is divided into a first display area 110 and a second display area. A sensor with a special function, such as an infrared sensor, is disposed under the first display area 110 . In order to enable the sensors with special functions to work normally, the transmittance of the light emitting units in the first display area 110 is generally set to be larger than that of the light emitting units in the second display area 120 .

[0047] Generally, the transmittance of the first display area 110 is increased by reducing the pixel density of the first light-emitting unit in the fir...

Abstract

The present application provides an electroluminescent display panel, a display device, and a method of manufacturing the display panel for improving a case where brightness of two display regions inthe display panel is uneven. The electroluminescent display panel is divided into a first display area and a second display area, the first display area includes a first light emitting unit, the second display area includes a second light emitting unit, the pixel density of the first light emitting unit is lower than the pixel density of the second light emitting unit, The thickness and / or material of the at least one functional film layer in the first light emitting unit is different from the thickness and / or material of the same functional film layer in the second light emitting unit so thatthe light emitting efficiency of the first light emitting unit is greater than the light emitting efficiency of the second light emitting unit.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an electroluminescent display panel, a display device and a method for preparing the display panel. Background technique [0002] The organic light emitting diode (Organic Light Emitting Diode, OLED) display panel in the electroluminescent display panel has the advantages of wide viewing angle, fast response speed, low power consumption, flexible display, and transparency. Therefore, it is widely used in terminals. display screen. In order to prevent the special function sensor in the terminal from occupying the display area of ​​the terminal, generally the special function sensor of the terminal is arranged below the first display area of ​​the display panel. [0003] In order to allow the light to reach the sensor through the first display area of ​​the display panel, so as to ensure the normal operation of the sensor. The transmittance of the first display area of...
