Polarizing plate and electronic device comprising same

Abstract

The invention discloses a polarizing plate and an electronic device comprising the same. The polarizing plate comprises a first protective film, a second protective film and a polarizing film and is clamped between the first protective film and the second protective film; the polarizing film comprises a first polarizing area and a second polarizing area which have different degrees of polarization; the degree of polarization of the first polarizing area is larger than 99.9% and smaller than 100%, and the light transmittance of the first polarizing area ranges from 40% to 45%; and the degree ofpolarization of the second polarizing area is not smaller than 90% and not larger than 99.9%, and the light transmittance ranges from 45% to 48%. The polarizing plate is suitable for the electronic device having a display element integrated with a camera module. According to the polarizing plate and the electronic device comprising the polarizing plate, the camera lens can be hidden while the high display ratio is achieved.

Description

technical field [0001] The invention relates to a polarizing plate, and in particular to a polarizing plate suitable for electronic devices, and an electronic device containing the polarizing plate. Background technique [0002] In recent years, various electronic devices such as personal computers, mobile communication devices and wearable devices have been widely used, and are equipped with various input devices or / and output devices in a limited space, such as displays, touch panels, sensors and Camera modules, etc., are the focus of related technology development. Currently, the structural design of an electronic device with a display integrated with a camera module has become the mainstream in the market. Such as figure 1 As shown in the top view, in a known electronic device with a display integrated with a camera module, in order to prevent the camera module from being visible outside the electronic device, the camera module 14 is disposed in the frame 18 of the dis...

Problems solved by technology

However, in order to prevent the polarizing characteristics of the polarizing plate 32 on the OLED display element 33 from affecting the light sensitivity of the lens 31 of the camera module 34, thereby deteriorating the photographic quality, the lens 31 of the camera module 34 must match the polarizing failure area 32b on the polarizing plate 32

However, when the photography function of the camera module 34 corresponding to the polarization failure area 32b is not in operation, the non-polarization degree of this area reduces the display quality when the area operates with a display function, and because of the high light transmittance of the polarization failure area 32b also Make the camera lens 31 below the area visible on the electronic device 3a
