Problems solved by technology

In the BPS design of color-resist stack shading, because the Main PS is located in the RB color-resist stack area, and the OD (Optical Density, optical density) value of BPS is lower than that of the traditional black matrix, so the BPS light-shielding block frame area is insufficiently shading, which affects the quality

Abstract

The invention provides a displayer and its preparation process. The displayer includes a display region and a non-display region. The preparation process includes the following steps that a substrate layer is provided, a first metal layer is formed on the substrate layer, a first insulating layer is formed on the first metal layer, and the first insulating layer is divided into a first region corresponding to the display region and a second region corresponding to the non-display region; a second metal layer corresponding to the first metal layer is formed on the first region of the first insulating layer, and the second metal layer and the first metal layer form a thin film transistor; a color resistance layer is formed on the thin film transistor, the portion, corresponding to the thin film transistor, of the color resistance layer is provided with a groove, a black optical spacer is arranged in the groove to form a main spacer, and at the same time, a black optical spacer with the same thickness is arranged on the second region of the first insulating layer and used for forming a light shielding block same as the main spacer in thickness, the thickness of the light shielding block of the second region, namely a frame region, of the first insulating layer is improved, the light shielding effect of the frame region is improved, and the quality of the displayer is improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display and its manufacturing process. 【Background technique】 [0002] Existing displays mainly include liquid crystal (Liquid Crystal Display, LCD) displays and OLED (Organic Light Emitting Diode, OLED) displays. Among them, OLED displays have many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, flexible display and large-area full-color display, etc. It is recognized by the industry as the display with the most development potential. [0003] In the traditional BOA (BM on Array) and POA (PS on Array) technologies, the spacer (PS) and the black matrix (BM) are different materials and different manufacturing processes. The shading of the frame glue area is BM, and the thickness is the same as The display area is close. [000...
