Problems solved by technology

However, increasing the width of the signal line will cause a loss in the pixel aperture ratio of the LCD panel
On the other hand, the increase in the thickness of the signal line is likely to cause a decrease in the uniformity of the film surface, and even affect the overall stress distribution of the circuit substrate, resulting in fragmentation of the substrate.
In other words, the current technical means still have their technological or optical design limitations to be broken through

Embodiment Construction

[0046] As used herein, "about," "approximately," "essentially," or "essentially" includes the stated value and the average within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art, taking into account the The measurement in question and the specific amount of error associated with the measurement (ie, limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or for example within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, "about", "approximately", "essentially" or "substantially" used herein may select a more acceptable range of deviation or standard deviation according to measurement properties, cutting properties or other properties, and may not use One standard deviation applies to all properties.

[0047] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. It will be understood that when an elem...

Abstract

A pixel array substrate comprises a substrate, a plurality of insulating patterns, a plurality of signal lines and a plurality of pixel structures. The insulating patterns are arranged on the substrate, and each insulating pattern is provided with at least one concave structure. The signal lines are respectively arranged on the insulating patterns and are respectively filled in at least one concave structure of one of the insulating patterns. The pixel structures are arranged on the substrate and electrically connected with the signal lines respectively. The invention also provides a pixel array substrate comprising a plurality of conductive patterns.

Description

technical field [0001] The present invention relates to a display technology, and in particular to a pixel array substrate. Background technique [0002] In recent years, with the development of display technology, consumer display devices (such as smart TVs, gaming displays) have continuously improved in display performance and functions, such as ultra-high resolution, high contrast, high frame rate (High frame rate) , anti-peeping or three-dimensional display and other functions. In order to meet the requirements of these specifications, the overall electrical properties of the driving circuit of the display device must be correspondingly improved. For example, in common pixel driving circuits, there are mostly problems of parasitic resistance and parasitic capacitance between the signal lines (such as data lines or scanning lines), active components and pixel electrodes, causing the waveform of the transmission signal to be delayed due to resistance and capacitance. (RC...
