Specifically, a first claw 21 is arranged on the display screen 2, and a first clamping hole 12 matched with the first claw 21 is arranged on the main control board 1. When the display screen 2 is mounted, the first claws 21 are deformed by a force so that the end portions thereof can pass through the first catching holes 12. After first jack catch 21 passed first card hole 12, first jack catch 21 no longer atress, under the effect of its self restoring force, first jack catch 21 will butt at the back of main control board 1 to fix display screen 2 on main control board 1, prevent that display screen 2 from droing. Optionally, first jack catch 21 can be provided with a plurality ofly, and a plurality of first jack catches 21 can be followed the circumference edge setting of display screen 2, correspondingly, first calorie of hole 12 also is provided with a plurality ofly, and each first jack catch 21 cooperates with the first card hole 12 that corresponds the position, is favorable to improving the fixed effect of display screen 2. In this embodiment, the display screen 2 is installed on the main control board 1 by the front side of the main control board 1, and the display screen 2 is convenient to disassemble and assemble. In other embodiments, the display screen 2 and the main control panel 1 may be fixed by other means such as fasteners.

Because have certain distance between pilot lamp and the display screen 2, the light that adjacent pilot lamp sent will mutual interference, lead to that the display content is fuzzy, influence the display effect. In order to solve the above problem, as shown in fig. 1 and fig. 2, a light-blocking bracket 4 is further disposed between the indicator light and the display screen 2. Light-proof support 4 can be fixed with main control board 1, is provided with a plurality of light trap 41 on light-proof support 4, and the light that every pilot lamp sent propagates through the light trap 41 that corresponds, and adjacent light trap 41 does not communicate, avoids light mutual interference in it to prevent scurrying light, improve display effect.

In particular, the light-blocking support 4 may be made of a material that is opaque to light, preventing light transmission. Alternatively, the light-blocking support 4 may be made of Polycarbonate (PC) or Polyethylene (PE). In other embodiments, the light-blocking holder 4 may be made of other light-blocking materials as long as it can block light, prevent light from scattering, and flee light.

In order to facilitate the assembly of the display assembly, a reasonable assembly gap needs to be reserved between the light-blocking support 4 and the display screen 2, and the interference between the light-blocking support 4 and the display screen 2 caused by dimension errors and assembly errors is prevented. Due to the existence of the assembly gap, the light-blocking bracket 4 cannot completely prevent light leakage, and if the distance between the adjacent light-transmitting holes 41 is too close, light leakage inevitably exists, which affects the display effect.

Therefore, in this embodiment, an elastic light-blocking pad 5 is further disposed between the light-blocking support 4 and the display screen 2, the light-blocking pad 5 is pressed between the light-blocking support 4 and the display screen 2, the light-blocking pad 5 is also provided with a light-transmitting hole 41 at a position corresponding to the indicator light, and light emitted by the indicator light sequentially passes through the light-transmitting holes 41 on the light-blocking support 4 and the light-blocking pad 5 and then is incident on the display screen 2.

In other embodiments, the light-shielding pad 5 may also be fixed to the light-shielding bracket 4 and/or the display screen 2 by glue or a fastener, so as to further improve the fixing effect of the light-shielding pad 5.

As shown in fig. 3, the light-shielding pad 5 may have a symmetrical structure. The structure of the light-insulating pad 5 on the end face facing one side of the display screen 2 is symmetrical to the structure of the light-insulating support 4 on the end face, so that the front and the back of the light-insulating pad 5 do not need to be distinguished during assembly, and the assembly is more convenient.

Further, the structures on each end face of the light-blocking pad 5 are symmetrically arranged. Specifically, taking the direction shown in fig. 3 as an example, the light-shielding pad 5 is symmetrical with respect to the center line extending left and right, and is symmetrical along the center line extending up and down, so that the assembly requirement is further reduced, and the assembly is more convenient.

Optionally, when the distance between adjacent indicator lights is long, the optical crosstalk distance is small. At this time, as shown in fig. 2, the light-blocking holder 4 may be provided with a ring-shaped light-blocking projection 45 protruding from the outer circumference of a part of the light-transmitting hole 41, and the light-blocking projection 45 may be integrally formed with the light-blocking holder 4, so as to simplify the process. When the light passing through the light holes 41 is scattered outwards, the scattered light can be absorbed by the light-isolating bosses 45, so that the scattered light is prevented from being further transmitted, the light is favorably collected, and the light fleeing in the adjacent light holes 41 is reduced. The size of the light-insulating pad 5 can be reduced by arranging the light-insulating boss 45, and the cost of the display assembly is favorably reduced. The reduction in size of the light-blocking pad 5 can make the deformation effect of the light-blocking pad 5 better, so as to improve the light-blocking effect.

In other embodiments, the light-blocking bosses 45 may be disposed outside the light-transmitting holes 41, and the light-blocking bosses 45 are inserted into the light-transmitting holes 41 of the corresponding light-blocking pad 3.

In order to make the light emitted by the indicator light more uniformly incident on the display screen 2, a light guide member 6 is further arranged between the computer board 3 and the light-shielding bracket 4. The light guide 6 may be made of a light guide material, such as polymethyl methacrylate (PMMA), which is also called acrylic or organic glass, and has high transparency, visible light transmittance up to 92%, and easy machining. The light emitted by the indicating lamp can be converted into a uniform surface light source by arranging the light guide part 6, so that the display effect is improved.

As shown in fig. 1 and 6, the light guide member 6 includes a plurality of light guide posts 61, and each light guide post 61 is inserted into the corresponding light hole 41 of the light-shielding support 4. Light that the pilot lamp sent spreads in the leaded light post 61 that corresponds, and the appointed area on the display screen 2 is evenly incided to the back, improves the homogeneity of light. In this embodiment, a plurality of leaded light post 61 all set up on light guide plate 63, can simplify the assembly process of a plurality of leaded light post 61, and a plurality of leaded light post 61 can once only realize the assembly through light guide plate 63, are favorable to improving assembly efficiency.

Optionally, the both ends of leaded light post 61 all bulge light guide plate 63 and set up to make things convenient for the one end of leaded light post 61 to align with the pilot lamp that corresponds, the other end stretches into in the light trap 41 that corresponds.

In this embodiment, the light guide member 6 can be fixed to the light-blocking support 4 in a clamping manner, so that the light guide member is convenient to disassemble and assemble. As shown in fig. 2 and 6, the light guide plate 63 is provided with a third claw 62 on a side facing the light-blocking support 4, and the light-blocking support 4 is provided with a third clamping hole 44 at a corresponding position.
