[0027] A normally black liquid crystal segment screen 10 comprises a segment display area 11 and an electro-optical transmissive area 12, wherein the electro-optical transmissive area 12 has a light-transmitting state and a light-shielding state. When the normally black liquid crystal segment screen 10 is in a power-on state, the electro-optical transmissive area 12 switches to the light-transmitting state, and when the normally black liquid crystal segment screen 10 is in a power-off state, the electro-optical transmissive area 12 switches to the light-shielding state.

[0028] The camera 20 is disposed on the back side of the electro-light-transmitting area 12 of the normally black liquid crystal segment screen 10 , with its lens facing toward the electro-light-transmitting area 12 .

[0029] The vehicle-mounted instrument of the utility model is provided with the electro-optically transparent area 12 in the normally black liquid crystal segment screen 10, and then the camera 20 is provided on the back of the electro-optically transparent area 12; the light and dark state of the electro-optically transparent area 12 is synchronized with the on-off state of the normally black liquid crystal segment screen 10, that is, as long as the normally black liquid crystal segment screen 10 is in the power-on state, regardless of whether it is displayed, it outputs a driving current to the electro-optically transparent area 12 to switch the electro-optically transparent area 12 to a light-transmitting state; when the normally black liquid crystal segment screen 10 is in the power-off state, the electro-optically transparent area 12 is not driven and is in a light-shielding state, light cannot pass through the electro-optically transparent area 12, and the driver cannot observe the camera 20 located on the back of the electro-optically transparent area 12; when the normally black liquid crystal segment screen 10 is in the power-on state, the switching electrode block 13 is synchronously driven and is in a light-transmitting state, light can pass through the electro-optically transparent area 12, and the camera 20 can photograph the driver or sense the external ambient light.

[0030] The normally black liquid crystal segment screen 10 refers to a type of liquid crystal segment screen that uses a black background with white characters, that is, the area that is not driven to display is black, and the area that is driven to display is white. When in a normal state (power-off state), the overall appearance is black and opaque.

[0031] like Figure 2 As shown, the normally black liquid crystal segment screen 10 includes a switching electrode block 13 arranged in the electro-light-transmitting area 12; when the normally black liquid crystal segment screen 10 outputs a driving current to the switching electrode block 13, the switching electrode block 13 generates a driving electric field to drive the liquid crystal material 18 located in the electro-light-transmitting area 12 to rotate, thereby switching the electro-light-transmitting area 12 from a light-shielding state to a light-transmitting state.

[0032] In this embodiment, the switching electrode block 13 is a circular electrode block, which is adapted to the shape of the lens of the camera 20, and the area of ​​the switching electrode block 13 is larger than the lens area of ​​the camera 20, so that the switching electrode block 13 can completely cover the lens of the camera 20.

[0033] Preferably, the camera 20 and the normally black liquid crystal segment screen 10 are bonded and fixed by an annular light-shielding glue 30. In addition to bonding and fixing the camera 20 and the normally black liquid crystal segment screen 10, the annular light-shielding glue 30 also plays a light-shielding role to prevent stray light (such as backlight) from entering the camera 20 through the gap between the camera 20 and the normally black liquid crystal segment screen 10, thereby improving the imaging quality of the camera 20.

[0034] In this embodiment, the annular light-shielding glue 30 is a black annular foam, which can also play a certain buffering and vibration-reducing role between the camera 20 and the normally black liquid crystal pen segment screen 10 .

[0035] The normally black liquid crystal segment screen 10 includes at least one segment electrode block 14 arranged in the segment display area 11; when the normally black liquid crystal segment screen 10 outputs a driving current to the segment electrode block 14, the segment electrode block 14 generates a driving electric field to drive the liquid crystal material 18 located in the segment display area 11 to rotate, so as to allow the backlight of the backlight module 40 to pass through, thereby lighting up the segment display area 11.

[0036] In this embodiment, Figure 1 As shown, the pen segment display area 11 includes an arc display area 111, a digital display area 112 and an icon display area 113. The arc display area 111 is formed by a plurality of square electrode blocks arranged in sequence in an arc shape, the digital display area is formed by a plurality of strip electrode blocks spliced ​​end to end in the shape of Arabic numerals, and the icon display area 113 is formed by a plurality of icon electrode blocks arranged in sequence according to preset positions; wherein, the electro-light-transmitting area 12 and the digital display area 112 are located in the area surrounded by the arc display area 111, the icon display area 113 is located in the arc opening of the arc display area 111, and the electro-light-transmitting area 12 and the icon display area 113 are respectively located on opposite sides of the digital display area 112.

[0037] The digital display area 112 is used to display the real-time speed of motorcycles, cars, etc., the arc display area 111 is used to gradually light up each square electrode block as the speed of the motorcycle, car, etc. increases, and the icon display area 113 is used to display fixed icons such as headlights, fog lights, and turn signals.

[0038] like Figure 2 As shown, a layer of black ink 15 is silk-screened inside the normally black liquid crystal segment screen 10, and the black ink 15 covers the remaining area of ​​the normally black liquid crystal segment screen 10 except the switching electrode block 13 and each segment electrode block 14, so that the normally black liquid crystal segment screen 10 presents a black background color.

[0039] The normally black liquid crystal segment screen 10 includes an upper polarizer 16 , an upper substrate 17 , a lower substrate 19 and a lower polarizer 110 which are arranged in sequence. The liquid crystal material 18 is sealed and filled between the upper substrate 17 and the lower substrate 19 .

[0040] The switching electrode block 13 and each segment electrode block 14 are arranged on a surface of the lower substrate 19 facing the upper substrate 17 , and the black ink 15 is arranged on a surface of the upper substrate 17 facing the lower substrate 19 . Embodiment 2

[0041] As an optimization solution of the first embodiment, in this embodiment, if Figure 3 As shown, the vehicle-mounted instrument further includes a backlight module 40 , which is disposed on the back side of the normally black liquid crystal segment screen 10 and corresponds to the segment display area 11 .
