[0028] As described above, in specific implementation, the plurality of LED chips in each first LED light emitting unit cavity 31 at least include one red light LED chip, one blue light LED chip and one green light LED chip, so as to realize RGB light emitting display.
[0029] As described above, in specific implementation, the positions of the first unit dam 32 and the second unit dam 52 are opposite, which on the one hand facilitates one-to-one correspondence of the front and rear LED light emitting units when the LED light emitting units are set, and on the other hand can reduce the area occupied by the projection of the front and rear unit dams on the transparent substrate 1, which is conducive to improving the transparent screen effect, in addition, the position of the first LED light emitting unit cavity 31 corresponds to the solid position of the second unit dam 52, which is conducive to enhancing the strength of the transparent substrate 1 at the first LED light emitting unit cavity 31 so as to set the IC chip and the LED chip, and the position of the second LED light emitting unit cavity 51 corresponds to the solid position of the first unit dam 32, which is conducive to enhancing the strength of the transparent substrate 1 at the second LED light emitting unit cavity 51 so as to set the IC chip and the LED chip, and the practicability is good.
[0030] As described above, in a specific implementation, the transparent substrate 1 is provided with front-to-back through holes, and the first unit dam 32 and the second unit dam 52, which are positioned opposite each other, are connected together through the front-to-back through holes, which makes the connection more stable.

Compared with the prior art, which first solders and mounts the LED chip to the LED bead holder to form an LED bead and then solders and mounts the LED bead to the substrate, this invention only requires one soldering and mounting process, eliminating the process of first soldering and mounting the LED chip to the LED bead holder to form an LED bead. This avoids the situation where secondary soldering and mounting is prone to damage and is conducive to improving production efficiency and has good practicality.
