Problems solved by technology

[0005] In the existing LED display panel, the LED chips of the same luminous color that are closer to each other usually have the same main luminous wavelength and brightness, and the closer the LED chips of the same luminous color, the dominant luminous wavelength, brightness, etc. Usually, the closer the LED display panel is, the different areas of the same color screen will have obvious differences in display effect when the LED display panel is displaying, which will affect the overall display effect of the LED display panel.

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 It is a schematic diagram of a partial structure of a light-emitting diode display panel in the related art. Such as figure 1 As shown, the display panel includes light-emitting diode chips 20 of three colors, and the light-emitting diode chips 20 marked with the same number in the figure emit the same color. This display panel needs to prepare three Bins before fabrication, each Bin includes a plurality of LED chips 20 of the same color, and the LED chips 20 in each Bin are produced from the same wafer A. During fabrication, the LED chips 20 are transferred from the three Bins to the carrier 10 in the sequence in which the LED chips 20 are arranged in the Bins. Since the light-emitting diode chips 20 of the same col...

Abstract

The invention discloses a light-emitting diode display panel. The light-emitting diode display panel includes a carrier board and multiple columns of light-emitting diode chips arranged along the row direction. The same column of light-emitting diode chips includes a plurality of light-emitting diode chips with the same color. The colors of the LED chips are different, and the LED chips of the same color are produced from different wafers. Since LED chips with the same color are produced from multiple wafers, LED chips of the same color produced from different wafers have different luminous parameters such as main luminous wavelength and brightness. The LED chips of the same color weaken the relationship between the distance between the LED chips and the luminous parameters of the LED chips, thereby improving the overall display effect of the LED display panel.
