Display panel and production method thereof

Abstract

The invention provides a display panel and a production method thereof. An area where two sides of a first corner in a display area are located is set as a cutting area; in the display area, an area where two sides of a second corner opposite to the first corner are located is set as an effective area, namely a non-cutting area; a peripheral signal line lead out from the display area and peripheral arrangement of the display area are arranged in the effective area where at least one of the two sides of the second corner is located; therefore, display screens in different sizes can be produced on the condition that only one light mask plate is adopted, development and production costs of display panel produces can be saved, development and design time for the display panel products can be shortened.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular may relate to a display panel used in the trial production process of the display panel and a preparation method of the display panel. Background technique [0002] At present, when display panel manufacturers decide to produce a certain type of display product, most of them adopt such figure 1 The development and production process shown includes: [0003] Step 11, determine the product model developed; [0004] Step 12, according to the appearance of the model (including display size, resolution, screen size, etc.), display performance (including transmittance, viewing angle, brightness, display mode, etc.), module specifications (such as backlight requirements, driver IC, etc.), Design the photomask, and design the distribution of the display area on the display substrate, the structure of the pixels, the layout of the peripheral circuit traces connected to the edg...

Problems solved by technology

[0008] The existing design and development process can only be put into use after product design, data transmission, mask production, and mask delivery; among them, design and mask production take the most time, which is not conducive to product quality. Rapid mass production to seize the market; in addition, due to the complexity of the circuit design of the TFT array substrate of display panel products, it is easy to make design mistakes, and most of the design defects can only be found through inspection after the product is produced. At this time, it is necessary to redesign or modify the photomask, which wastes a lot of time; and because the preparation cost of the photomask is extremely high, it occupies a large share of the production and development costs of the display panel, so the modification or redesign The photomask will increase the production cost, which is not conducive to the reduction of production cost, so that the product does not have a price advantage in the market competition
