In other words, the part of the third control signal line 134 blocked by the light-transmitting portion 7 is bent back without electrically connecting the fourth control signal line 135, the part of the third control signal line 134 blocked by the light-transmitting portion 7 bypasses the light-transmitting portion 7 and is electrically connected to the fourth control signal line 135, and only the part of the third control signal line 134 bypasses the light-transmitting portion 7, so that the winding width of the periphery of the light-transmitting portion 7 is small, the frame area near the light-transmitting portion 7 is also small, and the influence on the display area of the display panel assembly 10 is also small.

Referring to fig. 7, the display panel assembly 10 further includes a light shielding tube 8 disposed on the substrate 10.

The light shielding cylinder 8 is used for preventing light generated inside the display screen assembly 10 from entering the light transmission portion 7 to influence an optical signal collected by the optical device 50 below the light transmission portion 7, thereby improving the signal collection accuracy of the optical device 50.

The region surrounded between two adjacent control signal lines 13 extending in the Y-axis direction and two adjacent control signal lines 13 extending in the X-axis direction and the devices provided in the region form one pixel unit 11.

The area of the display area 101 other than the light-transmitting portion 7 is the effective display area of the display panel assembly 10, and the routing design of the peripheral side of the light-transmitting portion 7 reduces the winding width of the peripheral side of the light-transmitting portion 7, further reduces the frame area of the light-transmitting portion 7, and further improves the effective display area of the display panel assembly 10.

The following description will specifically describe an embodiment in which the display panel assembly 10 is a liquid crystal display panel, with reference to the accompanying drawings.

Referring to fig. 12, the structure of the present embodiment is substantially the same as that of the previous embodiment, and the main difference is that the display panel assembly 10 includes a transparent cover plate 6, an upper polarizer 41, a color filter substrate 10, a liquid crystal layer 42, an array substrate 43, a lower polarizer 44, and a backlight module 45, which are sequentially stacked.

Referring to fig. 13, the array substrate 43 is provided with pixel units 431 arranged in an array, a control signal line 13 (see fig. 7), a driving unit 17 (see fig. 7), and a pixel electrode 432. The layout of the control signal lines 13 and the connection between the driving unit 17 and the control signal lines 13 are the same as those in the previous embodiment, and are not described herein again. The pixel electrode 432 is disposed on the pixel unit 431.

Specifically, in this embodiment, the gate of the fifth driving transistor 435 is electrically connected to the fifth control signal line 136, the source of the fifth driving transistor 435 is electrically connected to the first control signal line 131, and the drain of the fifth driving transistor 435 is electrically connected to the pixel electrode 432. The display screen assembly 10 also includes a common electrode (not shown). The pixel electrode 432 and the common electrode are disposed on opposite sides of the liquid crystal layer 42. The display screen assembly 10 forms an electric field capable of controlling the deflection of liquid crystal molecules by applying voltages to the pixel electrode 432 and the common electrode, changes (modulates) the light transmittance of visible light emitted by the backlight module 45 by using the change of the arrangement direction of the liquid crystal molecules under the action of the electric field to complete electro-optic conversion, and completes the color reproduction of a time domain and a space domain by using different excitations of R (red), G (green) and B (blue) three-primary-color signals in the color film substrate 10 through the red, green and blue three-primary-color filter films, thereby controlling the transmission of light to realize the display function of the display screen assembly 10.

Further, referring to fig. 13, the fifth pixel unit 433 and the sixth pixel unit 434 are two pixel units 431 disposed in the same row and electrically connected to the same first control signal line 131.

When the first driving unit 171 transmits a low-level signal to the gate of the third switching element 437, the source and the drain of the third switching element 437 are disconnected. When the first driving unit 171 emits the first data voltage and transmits the first data voltage to the fifth and

sixth pixel units

433 and 434 through the first control signal line 131, the first driving unit 171 sends a low level to the gate of the third switching element 437 to turn off the third switching element 437, at which time the first data voltage is written in the fifth driving transistor 435. When the first driving unit 171 generates the second data voltage and transmits the second data voltage to the fifth and

sixth pixel units

433 and 434 through the first control signal line 131, the first driving unit 171 transmits a high level to the gate of the third switching device 437 to turn on the source and drain of the third switching device 437, at which time the second data voltage is written in the fifth and sixth driving

transistors

435 and 436. In this manner, writing of different voltage signals in the fifth drive transistor 435 and the sixth drive transistor 436 electrically connected to the same first control signal line 131 is achieved.

In other embodiments, the fifth pixel unit 433 may further include a fourth switching element (not shown) electrically connected between the first control signal line 131 and the fifth driving transistor 435. The fourth switching part has the same function as the third switching part 437. The fourth and third switches 437 may enable different voltage signals to be written in the fifth and sixth driving

transistors
