    Abstract: A double-sided display device includes a first liquid crystal panel for displaying images; a second liquid crystal panel opposite to the first liquid crystal panel, the second liquid crystal panel is configured for displaying the same image with the first liquid crystal panel; a backlight module between the first liquid crystal panel and the second liquid crystal panel, and the backlight module is configured for providing a surface light source to the first liquid crystal panel and the second liquid crystal panel; and wherein the first liquid crystal panel and the second liquid crystal panel share the same driving system. By adopting only one driving system, the first liquid crystal panel and the second liquid crystal panel are controlled to display the same images. The number of the signal input devices and the signal sources may be decreased such that the number of the integrated circuits may also be decreased.

    Abstract: A display inspection device includes a light source, a light condenser unit, a light splitter unit, and a photoelectric converter that are arranged, in sequence, externally of a display-to-be-inspected. The light condenser unit provides constant-frequency excitement to the inspection light beam so as to make constant-frequency variation of focus of the inspection light beam. The range of variation of the focus of the inspection light beam always covers a focus point on a surface of the display-to-be-inspected so that the inspection device possess an active focusing function, allowing a surface configuration, reflectivity, or defect of the display-to-be-inspected to be reflected in variation of intensity of a reflected light beam and also allowing the focusing point of the inspection light beam not to be constrained to focus on the surface of an objected-to-be-inspected thereby greatly increasing an inspection range of the device and improving inspection efficiency.

    Abstract: A liquid crystal panel and a liquid crystal display device are provided. The liquid crystal panel comprising array substrate and color filter substrate are corresponding to each other. The color filter substrate includes substrate and black matrix positioned on substrate. The liquid crystal panel comprises interval holding portion, an end of interval holding portion is contacted to black matrix, and another end of interval holding portion is contacted to array substrate for keeping distance between array substrate and color filter substrate. The interval holding portion is made by organic material has low elasticity modulus and high extension rate. It can ensures optical path difference without changed while the liquid crystal panel be curved. Therefore, enhances quality of display image. In addition, the method of manufacture liquid crystal panel is simplified in this invention such that could saves cost.

    Abstract: A blue-phase liquid crystal display panel includes a first substrate and a second substrate parallel to the first substrate. The first substrate is spaced apart from the second substrate. The first substrate includes a first base and a first electrode layer and a second electrode layer arranged close to one side of the second substrate. A first space is arranged between the first electrode layer and the second electrode layer, and a second space is arranged between the second electrode layer and the second substrate, and a channel is configured between the first space and the second space. The first electrode layer cooperatively operates with the second electrode layer to form an electrical field within the first space and a weight of the electrical field is parallel to the first substrate or the second substrate. In addition, a manufacturing method of the blue-phase liquid crystal display panel is disclosed.

    Abstract: The present invention relates to a GOA circuit. The GOA circuit comprises: a first thin film transistor (T1) to a fourteenth thin film transistor (T14), a first capacitor (C1) and a second capacitor (C2). The present invention adds a control unit consisted of thin film transistors (T9-T14) on the basis of the GOA circuit structure according to prior art, and a set of control signals (Select1, Select2) of which phases are opposite is introduced. The main function is to divide the gate output of the GOA circuit into two. In some special display mode, the frequency corresponded with Data signal will be halved, and the corresponding drive power consumption will be decreased. The present invention provides a GOA circuit, which can effectively reduce the layout space occupied by the GOA circuit for having a certain help to the development of the narrow frame technology.
