Example 2

The terminal device of embodiment 2 is substantially the same as that of embodiment 1 except that:

the plurality of optical fiber cores 11 constitute a plurality of optical fiber units each including a part of the plurality of optical fiber cores 11, the plurality of optical fiber units being arranged at different positions in the extending direction along the slit 13.

The control module adjusts the display information of the screen 12 according to the brightness difference information or the brightness value information received by the optical fiber unit.

Specifically, the control module may be the processor 380 shown in fig. 3, or an optical processor independent of the processor 380.

Divide into a plurality of optical fiber unit with optic fibre sinle silk 11, can carry out the block processing to the luminance information of every optic fibre sinle silk 11 that collects. For example, when the brightness information of one or several of the plurality of optical fiber cores 11 arranged at the same position (the same position refers to a continuous range and not to a point) is lower than a predetermined value, a specific display information (for example, a display direction) is adjusted regardless of the brightness information collected by the optical fiber cores 11 at other positions.

Referring to fig. 4, the plurality of optical fiber cores 11 in the extending direction of the slit 13 are divided into a first optical fiber unit 17 and a second optical fiber unit 18, and the first optical fiber unit 17 and the second optical fiber unit 18 are the optical fiber cores 11 of the opposite two edges, respectively.

Thus, the direction in which the screen 12 should be displayed can be determined according to the state of the user gripping the mobile phone.

When a user holds the mobile phone, the optical fiber cores 11 in the first optical fiber unit 17 are shielded, so that the control module can judge that the user holds the mobile phone directly according to the brightness information of some optical fiber cores 11 in the first optical fiber unit 17 or the brightness difference information of all the optical fiber cores 11 in the first optical fiber unit 17, and therefore, the display direction of the control screen 12 is vertical.

When the user holds the mobile phone in a horizontal direction, the optical fiber cores 11 in the second optical fiber unit 18 are shielded, so that the control module can judge that the user holds the mobile phone in the horizontal direction according to the brightness value information of some optical fiber cores 11 in the second optical fiber unit 18 or the brightness difference information of all optical fiber cores 11 in the second optical fiber unit 18, and thus the display direction of the screen 12 is controlled to be horizontal.

Certainly, when the control module judges the state of the user gripping the mobile phone, the control module can also be corrected by combining with functional modules of the terminal device, such as gravity sensing and the like.

In the present embodiment, the optical fiber core 11 is continuously arranged in the slit 13. Alternatively, the optical fiber core 11 may also be arranged in sections, e.g. only in the normal gripping position of the user.

Example 3

As shown in fig. 5, embodiment 3 provides a photoreception control method. The sensitization control method is applied to the terminal device of embodiment 1. The photosensitive control method comprises the following steps:

step 100: the optical fiber wire core collects brightness information outside the terminal equipment and transmits the brightness information to the control module;

step 200: the control module adjusts display information of the screen according to the brightness information.

According to the light sensing control method, the optical fiber wire cores arranged in the gap between the frame and the screen are used for transmitting light to the control module inside the terminal device, the control module can adjust display information of the screen according to brightness information collected by the optical fiber wire cores, and therefore the situation that a lighting module is arranged on a front panel of the terminal device is avoided, and the higher screen occupation ratio of the terminal device is achieved.

The luminance information here generally includes luminance value information and luminance difference information, and the display information of the screen may be a display direction, luminance, resolution, color difference, and the like of a picture on the screen. For example, if the terminal device is transferred to the place with insufficient light from the place with sufficient light, the light wire core transmits the brightness value information to the control module, and the control module judges that the external light of the terminal device is insufficient, so that the brightness of the screen is improved.

Alternatively, the plurality of optical fiber cores may constitute a plurality of optical fiber units, each of which includes a part of the plurality of optical fiber cores.

In this case, the light sensing control method further includes: the correspondence relationship of each kind of luminance information to each display information is set. For example, a change in the brightness value (one kind of brightness information) in a certain optical fiber unit corresponds to the screen being displayed as light, and a change in the brightness value (another kind of brightness information) in another optical fiber unit corresponds to the screen being displayed as dim. For example, the brightness difference (one kind of brightness information) between different optical fiber cores in one optical fiber unit corresponds to a higher screen display resolution, and the brightness difference (another kind of brightness information) between different optical fiber cores in another optical fiber unit corresponds to a lower screen display resolution.

Each fiber unit provides a kind of brightness information. And the control module adjusts the display information according to the corresponding relation.

In this way, by arranging a plurality of optical fiber units, the collected luminance information of each optical fiber core can be subjected to block processing.

The luminance information here may be luminance value information or luminance difference information or the like, and the display information of the screen may be a display direction, luminance, resolution, color difference, and the like of a picture on the screen.

Alternatively, the plurality of optical fiber cores 11 may be distributed at four edges of the screen 12, and the optical fiber cores 11 of the opposite two edges form one optical fiber unit. The specific arrangement can be seen in fig. 4.

Wherein each kind of brightness information corresponds to a display direction of a picture on a screen. The display direction of the corresponding picture is vertical when the brightness difference (brightness difference information) occurs between different optical fiber cores in the first optical fiber unit or some optical fiber cores in the first optical fiber unit are lower than a preset value (brightness value information). The display direction of the corresponding picture is horizontal when brightness difference (brightness difference information) occurs between different optical fiber cores in the second optical fiber unit or certain optical fiber cores in the second optical fiber unit are lower than a preset value (brightness value information).

The step 200 specifically includes: and the control module adjusts the display direction of the picture on the screen according to the corresponding relation.

Therefore, the direction to be displayed on the screen can be judged according to the state of the user holding the mobile phone.

When a user holds the mobile phone directly, the optical fiber cores in the first optical fiber unit can be shielded, so that the control module can judge that the user holds the mobile phone directly according to the brightness value information of some optical fiber cores in the first optical fiber unit or the brightness difference information of all the optical fiber cores in the first optical fiber unit, and the display direction of the control screen is vertical.

When a user holds the mobile phone transversely, the optical fiber cores in the second optical fiber unit can be shielded, so that the control module can judge that the user holds the mobile phone transversely according to the brightness value information of some optical fiber cores in the second optical fiber unit or the brightness difference information of all the optical fiber cores in the second optical fiber unit, and the display direction of the control screen is transverse.

Certainly, when the control module judges the state of the user gripping the mobile phone, the control module can also be corrected by combining with functional modules such as gravity sensing and the like.

In this embodiment, the optical fiber cores are arranged continuously in the gap. Alternatively, the optical fiber cores may also be arranged in sections, for example only in the normal gripping position of the user.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
