Abstract

The invention relates to the technical field of display, in particular to an organic light-emitting diode display panel, a display module and electronic equipment. An effective display area of the organic light-emitting diode display panel comprises at least one fingerprint identification area, the fingerprint identification area is used for enabling light received by an optical fingerprint sensorto pass through, and the light transmittance of the at least one fingerprint identification area is larger than that of other areas in the effective display area. Each fingerprint identification areacan be arranged corresponding to one or more optical fingerprint sensors in specific implementation. Due to the fact that the light transmittance of the fingerprint identification area is larger thanthat of other areas in the effective display area, light loss caused when light penetrates through the fingerprint identification area can be reduced, and the problem that the imaging quality of theoptical fingerprint sensor is reduced due to light loss can be solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an organic electroluminescent display panel, a display module and electronic equipment. Background technique [0002] In the current consumer electronics market, the appearance design of mobile phone products has developed towards the direction of high screen-to-body ratio. , which can improve the aesthetic appearance of the mobile phone and the user's operating experience to a certain extent. [0003] In order to obtain a higher screen-to-body ratio for mobile phones, the current common solution is to shorten or cancel the areas on the top and bottom of the screen on the front panel of the mobile phone. The area of ​​the front panel can be reduced while the screen area remains unchanged, thereby It can increase the proportion of the screen occupied area on the front panel. For mobile phones with fingerprint recognition function, when shortening or canceling the area...
