The application provides a display substrate, a preparation method, a display panel and a display device. The display substrate comprises an array substrate, at least one first pixel defining layer and at least one second pixel defining layer. The at least one first pixel defining layer is used for defining at least one sub-pixel unit. The at least one second pixel defining layer is arranged in the sub-pixel unit and is used for separating the sub-pixel unit into at least two independent sub-pixel regions. All the sub-pixel regions of the same sub-pixel unit are used for forming the same color sub-pixel by inkjet printing. The height of the second pixel defining layer is less than the height of the first pixel defining layer, so that when inkjet printing, the ink can flow across the second pixel defining layer and into other sub-pixel regions. Thus, a single drop of ink can be dispersed into different sub-pixel regions, so that the film thickness of the sub-pixel formed after the ink in the sub-pixel region is dried can be accurately adjusted to meet actual requirements.

The application provides a two-stage mapping method and system for driving a 6-color module by a 1-bit chip, acquires 6-color original image data including black, white, yellow, red, blue and green, performs neighborhood dithering processing on the 6-color original image data, divides pixels into foreground color and background color regions according to a weight threshold, encodes the 6-color data into 4-color foreground encoding in the first stage, loads a matching waveform to complete yellow, red and green color display, and then performs hardware drive shutdown and voltage retention on the colored pixels; in the second stage, 4-color background encoding is generated for the uncolored black, blue and white pixels and corresponding drive voltages are applied, while the colored regions are prevented from being disturbed; and stable 6-color display is realized. The application can reuse the 1-bit chip and the existing backplane, greatly reduces the cost, improves the display uniformity and environmental adaptability, and effectively suppresses defects such as color mixing and residual image.
