Embodiment 1

[0022] Such as figure 1 As shown, the vehicle display brightness adjustment system includes an upper block 1, a lower block 2, and a light-shielding film 3. The lower surface of the upper block 1 is provided with a slot-4, and the slot spacing of the slot-4 can be adjusted. , the card slot one 4 includes a fixed piece 20 and a locking piece 21, the fixed piece 20 is fixedly connected with the lower surface of the upper block 1, and the fixed piece 20 and the locking piece 21 are respectively provided with threaded holes, so The clamping piece 21 is connected with the fixing piece 20 through the threaded hole through the bolt, the two ends of the lower surface of the upper block 1 are provided with a hanging ear 5, and the hanging ear 5 is provided with a through hole 24, so A first rotating shaft 6 is arranged between the hanging lugs 5, and one end of the first rotating shaft 6 is provided with an anti-off piece 7, and the other end of the first rotating shaft 6 is connected ...

Embodiment 2

[0025]On the basis of Embodiment 1, the first hanging ear 5 is provided with a connecting hole 17, the second hanging ear 11 is provided with a spring 18, and one end of the spring 18 is provided with a hook 19, and the hook 19 of the spring 18 is connected to the connecting hole 17. The spring 18 is in tension. The upper block 1 and the lower block 2 are further fixed by the spring 18 to prevent the position of the upper block 1 or the lower block 2 from moving.

Embodiment 3

[0027] On the basis of Embodiment 1 and Embodiment 2, the slot one 4 includes a fixing piece 20 and a locking piece 21, the fixing piece 20 and the locking piece 21 are connected by bolts, and the locking piece is adjusted according to the thickness of the upper surface of the display screen 21 and the distance between the fixed piece 20, the card slot 2 10 includes the fixed piece 22 and the locking piece 23, the fixing piece 22 and the locking piece 23 are connected by bolts, and the locking position is adjusted according to the thickness of the lower surface of the display screen The spacing between the second sheet 23 and the second fixed sheet 22. It is suitable for display screens of various thicknesses, with a wide range of applications and simple and convenient operation.

The system comprises an upper block, a lower block and a photomask; the lower surface of the upper block is provided with first slots, the distance between the first slots can be adjusted, the two ends of the lower surface of the upper block are provided with first hangers respectively, a first rotating shaft is arranged between the first hangers, one end of the first rotating shaft is connected with a first rotating handle the first rotating shaft is provided with a first groove, and one end of the photomask extends into the first groove and is wound around the first rotating shaft; the upper surface of the lower block is provided with second slots, the distance between the second slots can be adjusted, the two ends of the upper surface of the lower block are provided with second hangers respectively, a second rotating shaft is arranged between the second hangers, one end of the second rotatingshaft is connected with a second rotating handle, the second rotating shaft is provided with a second groove, and the other end of photomask extends into the second groove and is wound around the second rotating shaft; and a surface color of the photomask becomes dark or light successively. Thus, a user can make adjustment according to a practical shielding effect conveniently.

Description

technical field [0001] The invention relates to an LED display screen, in particular to an automotive display screen brightness adjustment system. Background technique [0002] LED display (LED display): A flat panel display consisting of small LED module panels. LED, Light Emitting Diode (light emitting diode abbreviation). It is a diode made of a compound made of gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), and indium (In) by controlling the display mode of a semiconductor light-emitting diode. When electrons and holes Visible light can be radiated when recombined, so it can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide phosphide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitride diodes emit blue light. LED displays are generally used to display various information suc...
