Referring to fig. 1 and 2, in an embodiment, an electronic device 100 includes a display module 10 and a housing 20, and the display module 10 is mounted on the housing 20. The housing 20 is formed with a mounting cavity for mounting electronic components such as a battery, a circuit board, etc. of the electronic device 100. Electronic device 100 still includes camera module 30, and camera module 30 is covered by display module 10, and light can pass display module 10 and get into camera module 30 to adapt to the needs that camera module 30 carries out the function of leading camera, the user can carry out operations such as auto heterodyne, video conversation through camera module 30. The display module 10 can be used to display information and provide an interactive interface for users.

The display module 10 is an LCD panel, and as shown in fig. 3 to 5, the display module 10 includes a display panel 101, a backlight module 102, and a light guide plate 103. The backlight module 102 is disposed on a side of the display panel 101 away from the light emitting surface of the display module 10, the backlight module 102 is configured to provide a light source for the display of the display panel 101, the light guide plate 103 is disposed between the backlight module 102 and the display panel 101, and the light guide plate 103 is configured to guide the display panel 101 to the display panel 101, so as to meet the requirement of the display panel 101 for light emitting display.

As shown in fig. 3 to 5, the display panel 101 includes a display area AA including a first display area AA1 and a second display area AA2 except for the first display area AA 1. In some embodiments, first display area AA1 and second display area AA2 are contiguous with each other.

It should be noted that, the first display area AA1 may have a part of its edge adjacent to the second display area AA2, or may have its entire edge adjacent to the second display area AA2, as long as they are adjacent to each other, so that when they are displayed simultaneously, a complete display screen can be formed. For example, fig. 1 illustrates an electronic device in which the second display area AA2 is located at the periphery of the first display area AA 1. In the electronic device shown in fig. 2, a portion of the edge of the first display area AA1 is adjacent to the second display area AA 2.

As shown in fig. 6 and 7, the first display area AA1 includes a plurality of first pixel units, the second display area AA2 includes a plurality of second pixel units, each of the first pixel units and the second pixel units includes a plurality of sub-pixels, and the first pixel unit includes at least one W pixel 111d, so that light can pass through an area of the display panel 101 corresponding to the first display area AA1, where the W pixel 111d is disposed, and the light transmittance of the first display area AA1 is greatly improved by the W pixel 111d, thereby facilitating shooting by the camera module 30 corresponding to the first display area AA 1.

The arrangement density of the sub-pixels in the first pixel unit is greater than that of the sub-pixels in the second pixel unit, thereby effectively improving the resolution of the first display area AA 1. Thus, even if the W pixel 111d is disposed in the first display area AA1, the display effects of the first display area AA1 and the second display area AA2 can be close to each other, so as to maintain the overall texture of the picture displayed in the display area AA of the display panel 101, and improve the full-screen display effect.

The structure of the display panel 101 is not particularly limited as long as the display area AA can satisfy the display requirements. It should be noted that, after the first display area AA1 is modified from the conventional RGB design to the arrangement mode including the W pixels 111d, the color resistance of the display panel 101 corresponding to the first display area AA1 may be eliminated, and the circuits and liquid crystal portions of the LTPS are reserved, so as to achieve the normal display effect of the first display area AA 1.

The camera module 30 is disposed on a side of the display panel 101 away from the light-emitting surface of the display module 10, and the camera module 30 is opposite to the first display area AA1, so that when the first display area AA1 can use light to pass through, the camera module 30 can meet the shooting requirement of the electronic device.

In some embodiments, as shown in fig. 3, the backlight module 102 is provided with a first through hole 1021, and the first through hole 1021 penetrates through the backlight module 102 along a thickness direction of the backlight module 102. A light guide plate 103 is disposed between the backlight module 102 and the display panel 101, the light guide plate 103 is used for transmitting light emitted by the backlight module 102 to the second display area AA2, the light guide plate 103 is provided with a second through hole 1031, the first through hole 1021 and the second through hole 1031 are both opposite to the first display area AA1, a refraction element 104 is disposed in the second through hole 1031, and the refraction element 104 is used for transmitting light emitted by the backlight module 102 to the first display area AA1, so that the first display area AA1 and the second display area AA2 can both receive light from the backlight module 102.

The light-emitting surface 103b of the light folding member 104 forms an acute angle with the light-incident surface 103a of the light guide plate 103, so that the light rays are emitted to the first display area AA1 obliquely, the arrangement of the first through hole 1021 and the second through hole 1031 does not affect the normal display of the first display area AA1, and then the first through hole 1021 and the second through hole 1031 can be used for accommodating part of the structure of the camera module 30, thereby facilitating the light and thin design of the whole electronic device.

The light emitting surface 103b of the light folding member 104 may be a conical surface around the hole axis of the second through hole 1031, or may be a spherical arc surface around the hole axis of the second through hole 1031, as long as the light can be deflected toward the hole axis of the second through hole 1031, so that the light is incident to the first display area AA 1.

As shown in fig. 3 and 4, the light refraction member 104 is integrally formed with the light guide plate 103, at this time, the light refraction member 104 is equivalent to a part of the light guide plate 103, and the light emitting surface 103b of the light refraction member 104 is located on the light guide plate 103.

As shown in fig. 5, an independent light source 1022 is disposed on a side wall of the backlight module 102 corresponding to the first through hole 1021, and light emitted by the independent light source 1022 can exit to the first display area AA1 through the light exit surface 103b of the light folding member 104. Then, the independent light source 1022 is used to provide a light source for the first display area AA1, so that the display state of the first display area AA1 can be controlled by controlling the on/off of the independent light source 1022. For example, when the display module 10 displays normally, the independent light source 1022 and the backlight module 102 are both turned on, so that the independent light source 1022 provides light for the first display area AA1, and the backlight module 102 provides light for the second display area AA 2. If in some cases, when the shooting effect is severe, the independent light source 1022 may be turned off, so that the first display area AA1 is in a non-display state, so that the external light beam enters the camera module 30 from the corresponding position of the W pixel 111d of the first display area AA1, thereby avoiding the adverse effect of the independent light source 1022 on the imaging of the camera module 30, and then the camera module 30 may obtain a better imaging effect.

Certainly, in some embodiments, even when the independent light source 1022 is turned on, since the light emitted by the independent light source 1022 is emitted to the first display area AA1 through the light folding piece 104, and the imaging light beam of the camera module 30 is the ambient light from outside the electronic device, the influence of the light of the independent light source 1022 on the imaging effect of the camera module 30 is very limited, that is, even at this time, when the first display area AA1 displays, the camera module 30 can still realize the shooting function, so that when a user uses the camera module 30 to perform self-shooting, the first display area AA1 can normally display the shooting picture, and thus the display area AA of the display panel 101 formed by the first display area AA1 and the second display area AA2 can completely present the shooting picture of the camera module 30, and the use experience of the user is effectively improved.

It should be noted that the independent light source 1022 may be omitted, that is, the independent light source 1022 is used as a part of the backlight module 102, and then the first display area AA1 and the second display area AA2 may display the images simultaneously according to the image display requirement, so as to obtain a complete display image. Because the W pixel 111d of the first display area AA1 can effectively improve the permeability of the first display area AA1, even if the first display area AA1 is in a state of displaying a picture, the light of the external environment can still pass through the first display area AA1 to enter the camera module 30, so that the camera module 30 can maintain a good shooting effect.

For the first display area AA1, there are various pixel arrangements to realize display while satisfying the requirement of light transmission.

The first pixel unit includes R, G, and B sub-pixels 111a, 111B, and 111c, and the R, G, and B sub-pixels 111a, 111B, and 111c and the W pixel 111d are arranged in an RGB-W hybrid pixel array. Wherein, the R sub-pixel 111a represents a red sub-pixel, the G sub-pixel 111B represents a green sub-pixel, and the B sub-pixel 111c represents a blue sub-pixel.

The R, G, and B sub-pixels 111a, 111B, and 111c in the plurality of first pixel units are arranged in a plurality of RGB pixel arrays. The W pixels 111d in the plurality of first pixel units are arranged in a plurality of columns or a plurality of rows, and equally divide the plurality of RGB pixel arrays.

In the embodiment that the W pixels 111d in the plurality of first pixel units are arranged in a plurality of columns or a plurality of rows, the plurality of columns or a plurality of rows of W pixels are arranged at equal intervals, so that the arrangement of the W pixels 111d in the first display area AA1 is uniform, the overall light transmission effect of the first display area AA1 is uniform, and local bright spots or dark spots are avoided.

Taking the sub-pixel arrangement shown in fig. 7 to 9 as an example, the W pixels 111d in the first pixel units are arranged in multiple columns, and the multiple columns of W pixels 111d equally divide the RGB pixel arrays, that is, between every two adjacent columns of W pixels 111d, there are sub-pixel columns with equal number of primary colors. Therefore, good display colors during light emitting display of the R sub-pixel 111a, the G sub-pixel 111B and the B sub-pixel 111c can be obtained, meanwhile, the W pixel 111d is arranged uniformly, and the formed light transmission area is relatively large, so that the light transmittance of the first display area AA1 is relatively high, and the shooting effect of the camera module 30 is effectively ensured. Correspondingly, when the W pixels 111d in the first pixel units are arranged in multiple rows, the arrangement of the sub-pixels shown in fig. 7 to 9 is rotated by 90 °, and at this time, the multiple rows of W pixels 111d equally divide the multiple RGB pixel arrays, so that the first display area AA1 can meet the requirement of displaying images, and at the same time, the higher transmittance of the W pixels 111d can meet the requirement of light entering the camera module 30, so as to meet the shooting requirement of the camera module 30.

It should be noted that there are many possibilities for dividing the RGB pixel array into equal parts, which are related to the arrangement of the W pixels 111 d. For example, as shown in fig. 7, 3 columns of primary color generating sub-pixels, i.e., an R sub-pixel column, a G sub-pixel column, and a B sub-pixel column, are arranged between two adjacent columns of W pixels 111 d. As shown in fig. 8, two adjacent rows of W pixels 111d have 2 rows of sub-pixel columns with different primary colors, for example, arranged in an RGWBRWGBW manner in the first pixel unit. Referring to fig. 9, in the RGB pixel array, after each row has a sub-pixel row presenting a primary color, a W pixel row is arranged, that is, the first pixel unit is arranged in a RWGWBW manner.

In some embodiments, the R, G, and B sub-pixels 111a, 111B, and 111c are not regularly arranged in rows and columns in the RGB-W hybrid pixel array.

As shown in fig. 10, in the first direction of the RGB-W hybrid pixel array, a plurality of W pixels 111d are arranged at intervals, R, G, and B sub-pixels 111a, 111B, and 111c are alternately arranged at intervals of the plurality of W pixels 111d, in the second direction of the RGB-W hybrid pixel array, the second direction is perpendicular to the first direction, the plurality of R sub-pixels 111a and the plurality of W pixels 111d are alternately arranged on a first virtual line L1, the plurality of G sub-pixels 111B and the plurality of W pixels 111d are alternately arranged on a second virtual line L2, the plurality of B sub-pixels 111c and the plurality of W pixels 111d are alternately arranged on a third virtual line L3, and the first virtual line L1, the second virtual line L2, and the third virtual line L3 are arranged at intervals in the first direction. In this embodiment, the W pixels 111d are arranged around each of the R sub-pixel 111a, the G sub-pixel 111B, and the B sub-pixel 111c, so that the display effect of the first display area AA1 is more uniform, and the distribution uniformity of the W pixels 111d is improved as much as possible, thereby being beneficial to improving the light receiving uniformity of the camera module 30, and improving the imaging quality of the camera module 30.

Referring to fig. 11, the arrangement of the sub-pixels shown in fig. 11 is the same as that of the sub-pixels shown in fig. 10, except that the number of the sub-pixels in the selected area is different, the first display area AA1 is formed to have different shapes, and the arrangement angles of the sub-pixels are different. Specifically, the shape of the first display area AA1 presented on the display panel 101 is not limited, and may be rectangular, circular or elliptical. The edge of the first display area AA1 may be parallel or at an angle with respect to the edge of the electronic device. Taking the shape of the electronic device as a rectangular block structure as an example, as shown in fig. 1, the electronic device has 2 short sides 100a disposed oppositely and 2 long sides 100b disposed oppositely. When the display module 10 including the display panel 101 is installed in the electronic device, the first direction may be a direction parallel to the short side, a direction perpendicular to the short side, or a direction forming an acute angle with the short side.

The area of the W pixel 111d is equal to the areas of the R, G, and B sub-pixels 111a, 111B, and 111c, respectively, so as to facilitate the uniformity of the pixel arrangement. The shapes of the W pixel 111d, the R subpixel 111a, the G subpixel 111B, and the B subpixel 111c may be rectangular or circular, elliptical, or rectangular with rounded corners, which is not limited herein.

In one embodiment, as shown in fig. 12 to 14, the R, G, and B sub-pixels 111a, 111B, and 111c in the plurality of first pixel units are arranged in a plurality of RGB arrays, at least one of the R, G, and B sub-pixels 111a, 111B, and 111c is arranged in an area different from that of the other sub-pixels to form a missing region in the RGB array, and the W pixel 111d is disposed in the missing region. By using the structure, the original primary color sub-pixels, such as the R sub-pixel 111a, the G sub-pixel 111B or the B sub-pixel 111c, are made smaller, so that the W pixel 111d is arranged in the vacated missing area, the overall arrangement is extremely compact, no space waste is generated, and meanwhile, the display of the first display area AA1 can be adapted, and the light transmittance of the first display area AA1 can be improved to meet the shooting requirements of the camera module 30.

Two of the R, G, and B sub-pixels 111a, 111B, and 111c are arranged with an area S1, the other is smaller than S2, the W pixel 111d has an area S3, and S1 ≧ S2+ S3. With this configuration, the W pixel 111d occupies only a small area of the first display area AA1 to meet the requirement of light entering the camera module 30, and three primary colors are arranged in most of the first display area AA1 to ensure the normal display effect of the first display area AA 1.

The Sub-pixels in the first display area AA1 may use the R Sub-pixels 111a, the G Sub-pixels 111B, and the B Sub-pixels 111c in different rows or columns to realize color mixing, so as to achieve a Sub-Pixel blurring (SPR) display effect, and further improve the display image quality when the display panel 101 displays, so that the fusion degree of the display images in the first display area AA1 and the second display area AA2 is higher, and the overall texture of the display image in the display area AA is improved.

Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 101 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 101 and/or the backlight when the electronic device 100 is moved to the ear. As one of the motion sensors, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when the mobile phone is stationary, and can be used for applications of recognizing the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which may be further configured in the electronic device 100, detailed descriptions thereof are omitted.

The audio circuit 506 may provide an audio interface between the user and the electronic device 100 through a speaker, microphone. The audio circuit 506 can convert the received audio data into an electrical signal, transmit the electrical signal to a speaker, and convert the electrical signal into a sound signal to output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 506 and converted into audio data, which is then processed by the audio data output processor 508 and then sent to, for example, another electronic device 100 via the rf circuit 501, or output to the memory 502 for further processing. The audio circuitry 506 may also include an earphone jack to provide communication of a peripheral earphone with the electronic device 100.

Wireless fidelity (WiFi) belongs to short-range wireless transmission technology, and the electronic device 100 can help the user send and receive e-mail, browse web pages, access streaming media and the like through the wireless fidelity module 507, and provides wireless broadband internet access for the user. Although fig. 15 shows the wireless fidelity module 507, it is understood that it does not belong to the essential constitution of the electronic device 100, and may be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 508 is a control center of the electronic device 100, connects various parts of the whole electronic device 100 by using various interfaces and lines, and performs various functions of the electronic device 100 and processes data by running or executing an application program stored in the memory 502 and calling data stored in the memory 502, thereby performing overall monitoring of the electronic device 100. Optionally, processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor, which primarily handles operating systems, user interfaces, application programs, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 508.

The electronic device 100 also includes a power supply 509 to power the various components. Preferably, the power supply 509 may be logically connected to the processor 508 through a power management system, so that the power management system may manage charging, discharging, and power consumption. The power supply 509 may also include any component such as one or more dc or ac power sources, recharging systems, power failure detection circuitry, power converters or inverters, power status indicators, and the like.
