Problems solved by technology

However, in the actual process, due to process errors, such as the influence of the position accuracy of the gold ball, the poor alignment of the color filter substrate and the array substrate, the compression rate of the gold ball will be too small, resulting in poor current conduction
If there is no power-on detection device, it is impossible to judge whether the array substrate is supplied with voltage
This will cause liquid crystal alignment disorder, resulting in problems such as poor display quality of the liquid crystal panel.

Abstract

The invention discloses an energization detection device of a liquid crystal display panel. The liquid crystal display panel comprises: a color film substrate and an array substrate arranged oppositely. The color film substrate and the array substrate comprise display regions and non-display regions which are out of the display regions and surround the display regions. The energization detection device comprises a first detection pad, a second detection pad, and conducting pieces. The first detection pad is arranged on the non-display region of the color film substrate. The second detection pad is arranged on the non-display region of the array substrate. The conducting pieces are arranged between the color film substrate and the array substrate, and respectively contact the first detection pad and the second detection pad. The invention also discloses a liquid crystal display panel with the energization detection device. Through arranging the energization detection device, current variation in circuit loop can be monitored in real time, so that whether voltage is applied on the array substrate can be determined. Thus, in liquid crystal alignment, voltage state of the array substrate can be obtained in time, so that problems of poor display quality of the liquid crystal panel generated by disorder of liquid crystal alignment is prevented.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a liquid crystal panel and a power-on detection device thereof. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of flat panel displays. Among many flat panel displays, liquid crystal displays (LCD for short) have high space utilization efficiency and low power consumption. , no radiation and low electromagnetic interference and many other superior characteristics have been applied in all aspects of production and life. [0003] A liquid crystal display usually includes a liquid crystal panel and a backlight module disposed opposite to each other. Since the liquid crystal panel cannot emit light, the backlight module needs to provide uniform light to the liquid crystal panel so that the liquid crystal panel can display images. A liquid crystal panel usually inc...
