A Light-Sensor (Light-Sensor) generally comprises a Light source, an optical path and a photoelectric element, and the Light-Sensor adopts the photoelectric element as a detection element. The measured light intensity variations are first converted into variations of the optical signal, which is then further converted into an electrical signal by means of a photoelectric element.

A light sensor commonly used in a terminal device is an ambient light sensor, which helps a display to provide a soft picture. When the ambient brightness is high, the LCD using the ambient light sensor will automatically adjust to high brightness. When the external environment is dark, the liquid crystal display can be adjusted to be low in brightness, and the screen brightness can be automatically adjusted through the light sensor.

In the present embodiment, the sensor 20 is a color temperature light sensor. That is, the sensor 20 may function as a color temperature sensor or a light sensor. The color temperature sensor and the light sensation sensor are integrated on the sensor 20, so that the stacking space of the sensor in the terminal equipment can be reduced, the color temperature light sensation sensor is low in development difficulty, easy to assemble and install and low in cost.

In this embodiment, the sensor 20 is a color temperature light sensor, and therefore the color temperature light sensor is provided with a photodiode, the photodiode is only used for receiving light and cannot emit light, the photodiode converts the intensity change of the received light into an electrical signal, and transmits the electrical signal to a processor of the terminal device, so as to analyze and process the electrical signal, and send a relevant instruction to be linked with other parts in the terminal device.

As further shown in fig. 1 to 5, the light guide bar 10 includes: a first face 11 and a second face 12, the first face 11 and the second face 12 being opposite and parallel.

The color temperature light sensor is accommodated in the accommodating groove 13, and as can be seen from the above, the color temperature light sensor has a photodiode, the position of the photodiode corresponds to the position of the light inlet pillar 14 connected with the second surface 12, and the light entering the accommodating groove 13 vertically corresponds to the photodiode of the color temperature light sensor, so that the photodiode can receive external light in the largest range, the sensitivity of the color temperature light sensor is improved, and the user experience is improved.

In addition, the vertically arranged light entering column 14 is aligned with the photodiode of the color temperature light sensor, so that the light path of the light entering column 14 is aligned with the photodiode, and the field of view performance and consistency of the whole sensor assembly are improved.

In some embodiments, the light input pillar 14 is provided with a light guide groove 141 at an end away from the first surface 11, a bottom wall of the light guide groove 141 is a light input surface, and the light input surface is parallel to the first surface 11.

Specifically, the end of the light entering pillar 14 far away from the first surface 11, that is, the end of the light entering pillar 14 abutting against the screen assembly 30, is provided with the light guiding groove 141 at the end, so that the notch of the light guiding groove 141 abuts against the back surface of the screen assembly 30, the bottom wall (that is, the inner wall close to the second surface 12) of the light guiding groove 141 is a light inlet surface, the light inlet surface is parallel to the first surface 11, the second surface 12 and the screen cover plate, and it can still be ensured that external light rays vertically enter the light entering pillar 14.

Therefore, light rays emitted by the screen can be further prevented from entering the light inlet surface of the light inlet pillar 14, heat or temperature generated by the screen or other parts is also prevented from being conducted to the color temperature light sensor, and the sensitivity of the color temperature light sensor is further improved.

The black opaque material may be black ink, and the black ink is attached to the surface of the first surface 11 of the light guide pillar 10 and the outer surface of the light incident pillar 14 by coating. In addition, the ink adhesion of the black ink needs to meet the test requirements. In some embodiments, the first surface 11 of the light guide bar 10 is provided with a laser etching area for marking the model or code of the light guide bar 10, and the light transmittance after laser etching in the laser etching area should be not less than 90%.

Further, the side wall of the light guide bar 10 and the first surface 11 may be coated with black ink, so as to further block light from other angles, and in addition, except the light entrance surface and the area corresponding to the photodiode on the top wall of the accommodating groove 13, other positions may be coated with black ink.

Specifically, since the shape, size and position of the boss 15 correspond to the accommodating groove 13, the boss 15 protrudes from the first surface 11, so that the height of the accommodating groove 13 can be increased, and the color temperature light sensor can be accommodated in the accommodating groove.

In addition, the first surface 11 is stepped by providing the boss 15 on the first surface 11. Only set up boss 15 in holding tank 13 department, can reduce the material cost of leaded light post 10, reduce the weight of leaded light post 10 and reduce the thickness of leaded light post 10 to be favorable to piling up of terminal equipment 100 inner space. In addition, when the light guide pole 10 is assembled in the terminal device 100, the first surface 11 of the light guide pole 10 can also abut against the middle frame, so that the movement of the light guide pole 10 towards the screen assembly 30 is limited, the position of the light guide pole 10 on the middle frame 40 is more stable, and the light path of the light guide pole 10 is ensured to correspond to or be consistent with the photodiode of the sensor 20.

Specifically, when the light guide pillar 10 is installed in the middle frame 40, the light incident pillar 14 of the light guide pillar 10 abuts against the back surface of the screen cover plate 31, and therefore, when the middle frame 40 is fixed to the screen cover plate 31 of the screen assembly 30 through glue dispensing, the distance between the edges of the light guide pillar 10 and the middle frame 40 can be increased, so that the glue accommodating path or width is increased, and glue is prevented from overflowing into the light guide groove 141 of the light incident pillar 14 due to the fact that the glue accommodating path or width is insufficient.

Further, the inclination angle of the first inclined surface 142 of the light input rod 14 and the inclination angle of the second inclined surface 151 of the boss 15 are inclination angles with respect to the longitudinal direction of the cellular phone. Therefore, after the glue overflows the second inclined surface 151 of the boss 15, the inclination angle of the first inclined surface 142 is greater than that of the second inclined surface 151, so that the glue accommodating path or width between the light-entering pillar 14 and the middle frame 40 is greater, more glue can be accommodated, and the glue is further prevented from overflowing into the light guide groove 141 of the light-entering pillar 14 due to the insufficient glue accommodating path or width.
