[0059] Specifically, as shown in FIG. 1, Figure 5 as shown in FIG. 1, Figure 5 FIG. 1 shows a front view of a partial structure of an LED display module according to an embodiment of the present application, Figure 5 The LED display module shown in FIG. 1 includes 2*2 arrayed LED display devices 2, and a mask 3 filled in the gap between adjacent LED display devices 2, adjacent vertical colloid separation grooves 43 are connected to vertical mask grooves 32, and adjacent horizontal colloid separation grooves 43 are connected to horizontal mask grooves 32, that is, adjacent vertical colloid separation grooves 43 and vertical mask grooves 32 are continuously connected in head-to-tail in the vertical direction, and adjacent horizontal colloid separation grooves 43 and horizontal mask grooves 32 are continuously connected in head-to-tail in the horizontal direction.

[0060] This approach considers that after LED display devices are surface-mounted to form an LED display module, crosstalk still exists between the outermost pixel units of adjacent LED display devices. Therefore, a mask is filled into the gaps between adjacent LED display devices. Furthermore, since the mask needs to fill the gaps between LED display devices as much as possible, the width of the mask needs to be close to the patch spacing of the LED display module. However, this patch spacing is often larger than the size of the colloid units in the LED display devices. When the mask fills the gaps, the width of the colloid units on the LED display devices differs from that of the mask, resulting in poor overall structural consistency. This leads to poor color consistency in the emitted light and inconsistent black screen appearance of the LED display module, affecting its display performance. Therefore, a mask unit is designed on the mask, with mask grooves around the edges of the mask unit. This ensures that each mask unit is the same size as the colloid unit, and the mask grooves are the same width and depth as the colloid separator grooves, with continuous connections end-to-end. This effectively improves the color consistency in the emitted light and consistent black screen appearance of the LED display devices, optimizing their display performance.

[0062] Specifically, such as Figure 6 As shown, Figure 6 for Figure 2 The enlarged schematic diagram at point a shows that the width w1 of the colloidal separator 43 is 0.05mm-0.4mm, and can be any or more of the following values: 0.05mm, 0.1mm, 0.2mm, 0.3mm, and 0.4mm.

[0063] In an optional implementation of this embodiment, the width of the mask groove 32 is 0.05mm-0.4mm.

[0064] Specifically, such as Figure 6 As shown, the width w2 of the mask groove 32 is 0.05mm-0.4mm, and can be any or more of the following values: 0.05mm, 0.1mm, 0.2mm, 0.3mm, and 0.4mm.

[0065] In an optional implementation of this embodiment, the width of the colloid separator groove is the same as the width of the mask groove.

[0066] Specifically, the width w1 of the colloid separator 43 is the same as the width w2 of the mask groove 32.

[0067] In an optional implementation of this embodiment, the depth of the colloidal separator 43 is 0.02mm-1mm.

[0074] In one optional implementation of this embodiment, any group of pixel units includes a red LED chip, a green LED chip, and a blue LED chip.

[0075] In summary, Embodiment 1 of this utility model provides an LED display module. By dividing and slotting adjacent pixel units of a single LED display device to form a colloidal separation groove, cross-lighting between pixel units on a single LED display device is effectively prevented.
