    Ultra Clear Glass Panel for Glass Substrates as Mini LED Backplanes


    Compared with the PCB substrate, the glass substrate has many advantages:

    • The thermal conductivity of the PCB material is not as good as that of the glass, and when the number of LED chips increases, the service life of the LED will be reduced; the glass substrate has the characteristics of good flatness and low expansion and contraction coefficient, which can better support COB packaging of Mini LED chips, and when the thickness of the PCB board is less than 0.4mm, when the LED chip is packaged on the PCB substrate, due to the different thermal expansion coefficients of the packaging glue and the PCB material, there may be a problem of glue cracking;

    • When used, the glass base can achieve a narrow frame and low OD value (the distance between the lower surface of the diffuser and the upper surface of the circuit board), so that the TV can be made thinner and more fashionable;

    • The glass base can make the area of the backplane smaller as needed Large, infinite splicing can be achieved, while the PCB version is difficult to achieve;

    • In addition, the cost of the glass substrate is relatively lower compared to the PCB substrate.
