More Information
Summary:The invention relates to a display panel and a preparation method thereof. The preparation method of the display panel comprises the steps that an LED substrate is provided, and the LED substrate comprises a TFT backboard and a plurality of LED chips arranged at intervals; a first substrate is provided, and a reflecting layer and a first barrier layer are formed on the first substrate; and the first substrate and the LED substrate are attached in an aligned mode. According to the preparation method of the display panel, the reflecting layer is prepared on the first substrate, so that uneven film thickness of the reflecting layer caused by the fact that the reflecting layer is prepared on the LED chip can be avoided, and the display effect of the display panel is improved. Meanwhile, the first barrier layer is firstly formed on the first substrate, and then the first substrate and the TFT backboard are aligned and attached, so that the binding stability of the TFT backboard and the LED chips can be prevented f
