4results about How to "Avoid cross-color" patented technology

The application relates to a color blocking agent for immunohistochemical multiplex sequential staining and application thereof, and belongs to the biomedical technology field. The color blocking agent is mainly composed of a buffer, an oxidizing agent and an eluent. The color blocking agent is used for immunohistochemical multiplex sequential staining, can effectively prevent cross staining, is suitable for a full-automatic immunohistochemical machine, is mild in condition and does not cause damage to tissues, and can be widely applied to full-automatic multiplex sequential staining in immunohistochemical pathological examination.

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.

The application relates to an integrated plastic wind guide cover injection molding method and a mold thereof, and relates to the technical field of injection molds.The method comprises the following steps: collecting mold information and oil information in response to a mold closing completion signal; determining a connecting portion wall thickness, a contact threshold value and a breaking value according to the mold information; matching an oil threshold value through the oil information; controlling an oil brush preset below a blade to move upwards and collecting a capacitance value until the capacitance value is greater than the breaking value, and defining the capacitance value at the moment as a contact capacitance value; controlling the blade to move based on the connecting portion wall thickness; injecting glue into a hard glue cavity in response to a blade stop signal; controlling the blade to reset based on the connecting portion wall thickness in response to a cooling completion signal, and then injecting glue into a soft glue cavity, and completing integrated injection molding operation after cooling. The application has the effects of avoiding color mixing and improving product quality.
