The second sub-pixel column includes a plurality of second sub-pixel groups, the second sub-pixel group includes a second sub-pixel and a third sub-pixel, and along the first direction, the second sub-pixels and the third sub-pixels in the second sub-pixel column are arranged alternately, and the first sub-pixel is configured to form a pixel unit with two second sub-pixel groups for displaying.

• H10K 59/35 - Devices specially adapted for multicolour light emission comprising red-green-blue [RGB] subpixels
• G09G 3/3225 - Control arrangements or circuits, of interest only in connection with visual indicators other than cathode-ray tubes for presentation of an assembly of a number of characters, e.g. a page, by composing the assembly by combination of individual elements arranged in a matrix using controlled light sources using electroluminescent panels semiconductive, e.g. using light-emitting diodes [LED] organic, e.g. using organic light-emitting diodes [OLED] using an active matrix
• H10K 71/16 - Deposition of organic active material using physical vapour deposition [PVD], e.g. vacuum deposition or sputtering
• C23C 14/04 - Coating on selected surface areas, e.g. using masks
