TECHNICAL FIELD

The present disclosure relates to, but is not limited to, the technical field of display, in particular to a detachment device for a spliced display device and a detaching method thereof.

BACKGROUND

With the development of science and technology, spliced display devices are widely used. Spliced display devices are usually composed of several independent display units, and there is a splicing gap between adjacent display units.

As the splicing gap of the spliced display device is getting smaller and smaller, when the display unit in the middle part of the spliced display device is defective and needs to be replaced, in order to prevent the occurrence of defective operations such as rubbing on the normal display unit around the defective display unit during the process of detaching the defective display unit, it is necessary to start detaching the display unit at the edge of the spliced display device until it is detached to the position of the defective display unit, resulting in waste of operation, and a large quantity of detaching processes may also cause new defective operations.

DETAILED DESCRIPTION

To make objectives, technical solutions, and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It is to be noted that implementations may be practiced in a plurality of different forms. Those of ordinary skills in the art may easily understand such a fact that implementations and contents may be transformed into various forms without departing from the purpose and scope of the present disclosure. Therefore, the present disclosure should not be explained as being limited to contents described in following implementations only. The embodiments in the present disclosure and features in the embodiments may be combined randomly with each other if there is no conflict.

In the drawings, a size of a constituent element, a thickness of a layer, or a region is exaggerated sometimes for clarity. Therefore, one implementation of the present disclosure is not necessarily limited to the sizes, and shapes and sizes of various components in the drawings do not reflect actual scales. In addition, the drawings schematically illustrate ideal examples, and one implementation of the present disclosure is not limited to shapes, numerical values, or the like shown in the drawings.

Ordinal numerals such as “first”, “second”, and “third” in the specification are set to avoid confusion between constituent elements, but not to set a limit in quantity.

In the specification, for convenience, wordings indicating orientation or positional relationships, such as “middle”, “upper”, “lower”, “front”, “back”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, and “outside”, are used for illustrating positional relationships between constituent elements with reference to the drawings, and are merely for facilitating the description of the specification and simplifying the description, rather than indicating or implying that a referred device or element must have a particular orientation and be constructed and operated in the particular orientation. Therefore, they cannot be understood as limitations on the present disclosure. The positional relationships between the constituent elements may be changed as appropriate according to directions for describing the various constituent elements. Therefore, appropriate replacements may be made according to situations without being limited to the wordings described in the specification.

In the specification, unless otherwise specified and defined explicitly, terms “mount”, “mutually connect”, and “connect” should be understood in a broad sense. For example, a connection may be a fixed connection, or a detachable connection, or an integrated connection. It may be a mechanical connection or an electrical connection. It may be a direct mutual connection, or an indirect connection through middleware, or an internal communication between two elements. Those of ordinary skills in the art may understand specific meanings of these terms in the present disclosure according to specific situations.

In the specification, a transistor refers to an element which at least includes three terminals, i.e., a gate electrode, a drain electrode and a source electrode. The transistor has a channel region between the drain electrode (drain electrode terminal, drain region, or drain) and the source electrode (source electrode terminal, source region, or source), and a current can flow through the drain electrode, the channel region, and the source electrode. It is to be noted that, in the specification, the channel region refers to a region through which the current mainly flows.

In the specification, a first electrode may be a drain electrode, and a second electrode may be a source electrode. Or, the first electrode may be a source electrode, and the second electrode may be a drain electrode. In cases that transistors with opposite polarities are used, a current direction changes during operation of a circuit, or the like, functions of the “source electrode” and the “drain electrode” are sometimes interchangeable. Therefore, the “source electrode” and the “drain electrode” are interchangeable in the specification.

In the specification, “electrical connection” includes a case that constituent elements are connected together through an element with a certain electrical effect. The “element with the certain electrical effect” is not particularly limited as long as electrical signals may be sent and received between the connected constituent elements. Examples of the “element with the certain electrical effect” not only include electrodes and wirings, but also include switch elements such as transistors, resistors, inductors, capacitors, other elements with various functions, etc.

In the specification, “parallel” refers to a state in which an angle formed by two straight lines is above −10° and below 10°, and thus also includes a state in which the angle is above −5° and below 5°. In addition, “perpendicular” refers to a state in which an angle formed by two straight lines is above 80° and below 100°, and thus also includes a state in which the angle is above 85° and below 95°.

In the specification, a “film” and a “layer” are interchangeable. For example, a “conductive layer” may be replaced with a “conductive film” sometimes. Similarly, an “insulation film” may be replaced with an “insulation layer” sometimes.

In the present disclosure, “about” refers to that a boundary is defined not so strictly and numerical values within process and measurement error ranges are allowed.

At present, although the display market is dominated by Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) display, due to the limitations in substrate size, preparation devices, process, etc., it is difficult for LCD and OLED to implement large-size display. In contrast, Micro LED/Mini LED display may implement large-size display by splicing, which can break the size limitation.

An embodiment of the present disclosure provides a detachment device for a spliced display device, wherein the spliced display device includes a first display unit and a second display unit adjacent to the first display unit, wherein the first display unit and the second display unit are spliced with each other; the detachment device for spliced display device includes:a detachment mechanism disposed to be connected with the first display unit to drive the first display unit to move along a direction away from or close to a plane where the spliced display device is located;at least one moving device, wherein the moving device includes a moving frame located outside the detachment mechanism and an adjustment member disposed on the moving frame, the moving frame is connected with the second display unit, the adjustment member abut against the detachment mechanism, and on the plane where the spliced display device is located, the moving frame drives the second display unit connected with the first moving device to move along a direction away from the first display unit through the adjustment member.

In an exemplary embodiment, as shown inFIG.5, the spliced display device1includes a plurality of display units101spliced to each other with splicing gaps102disposed between adjacent display units101. The display unit101may employ an LED display unit. The LED display unit may be a Micro LED display unit or a Mini LED display unit. Because LEDs have the advantages such as self-luminescence, wide viewing angle, fast response, simple structure, small volume, lightness and thinness, energy saving, high efficiency, long service life, clear light, etc., a spliced display device can achieve high resolution (such as Pixels Per Inch, PPI).
