Fig. 1C is a side view of the driving circuit board and the display panel after being pressed together in the related art.

As shown in fig. 1A to 1C, when the driving circuit (IC) in the related art is pressed on the display panel, a gap is formed between the blank area near the contact point on the driving circuit board 220 and the display panel 210, and since the driving circuit board 220 has a certain toughness, when the pressing force is too large, the vicinity of the contact point is easily warped, which causes the contact point to be in poor contact with the display panel 10, and the connection reliability is poor.

In view of the above problems, embodiments of the present disclosure provide a display panel, which supports at least a portion of a non-contact position of a driving circuit board by providing a supporting member between the display panel and the driving circuit board, thereby preventing the driving circuit board from warping when being pressed against the display panel and ensuring connection reliability.

As shown in fig. 2 to 4, the display screen of the embodiment of the present disclosure may include a display panel 10, a driving circuit board 20, and a supporting member 13.

The display panel 10 includes a display surface for displaying a screen and a back surface opposite to the display surface. The display panel 10 may be a liquid crystal display panel, an organic light emitting diode display panel, and includes a display region for displaying information and a non-display region, wherein a portion of the non-display region is used for pressing a driving circuit (IC) on the driving circuit board 20 to achieve electrical conduction. The non-display area may surround at least one edge of the display area. For example, the non-display region may be provided around the peripheral edge of the display region, and the driving circuit may be pressed at an arbitrary position of the non-display region.

The driving circuit board 20 is electrically connected to the display panel 10, and the driving circuit on the driving circuit board 20 is used for driving the display panel 10 to display the screen information.

The driving circuit board 20 is provided with a plurality of protruding contacts, which can be used as a driving circuit (IC) for being pressed and fixed with the display panel 10 so as to be electrically connected with the display panel 10.

The supporting member 13 is located between the display panel 10 and the driving circuit board 20, and corresponds to at least a partial non-contact position of the driving circuit board 20.

The driving circuit board 20 has a contact position and a non-contact position other than the contact position, the contact position is provided with a contact for electrically connecting with the display panel 10, the supporting member 13 is disposed corresponding to the non-contact position, and the supporting member 13 is not electrically connected with the display panel 10, thereby supporting the driving circuit board 20. The support member 13 may be formed of an insulating material.

There may be a plurality of contactless positions on the driving circuit board 20, and the supporting member 13 may be disposed at one or more of the contactless positions; a support member 13 corresponding to one or more contactless positions may also be provided on the back of the display panel 10.

The supporting member 13 supports the contactless position of the driving circuit board 20, and when the driving circuit board 20 is pressed on the display panel 10, the contactless position between the driving circuit board 20 and the display panel 10 is filled with the supporting member 13, so that the deformation of the driving circuit board 20 can be effectively inhibited, and the driving circuit board is locally warped at the position close to the contact point, therefore, the contact point on the driving circuit board 20 can be more fully electrically contacted with the display panel 10, and the connection reliability is enhanced.

In some embodiments, the contactless position may be located in a blank area of the driving circuit board 20 where no contact is provided.

The driving circuit board 20 includes a blank region, which may be a region other than the protruding contact, i.e., a region where no contact is provided, and also a non-electrical contact region on the driving circuit board 20. The blank area on the driving circuit board 20 may have a plurality of positions, and the plurality of blank areas may be continuous or dispersed according to the arrangement position and the arrangement manner of the contacts on the driving circuit board. In one example, the driving circuit board 20 has a contact area on which a plurality of protruding contacts, i.e., a contact area formed of a plurality of contacts, are arranged, and a blank area.

The supporting member 13 is located between the display panel 10 and the driving circuit board 20, corresponds to the blank area of the driving circuit board 20, and is used for supporting the blank area on the driving circuit board 20 when the driving circuit board 20 is pressed on the display panel 10. The support member 13 may be disposed adjacent to the contacts. Corresponding to the position of the blank area, one supporting member 13 may be provided at each blank area, and each blank area may be filled with one supporting member 13 to provide support during the press-fitting process. A plurality of discrete support members 13 may be further provided at each of the blank regions corresponding to the positions of the blank regions, and each of the blank regions is filled with the plurality of discrete support members 13 to provide support during the press-fitting process. In addition, the plurality of dispersed supporting members 13 may be arranged regularly or irregularly, and the size of each supporting member 13 may be the same or different.

In the process of pressing the driving circuit board 20 onto the display panel 10, an Anisotropic Conductive Film (ACF) may be coated on a corresponding position of the display panel 10 (e.g., a non-display area of the display panel 10), and then the driving circuit board 20 may be pressed onto the display panel 10 by a pressing head, so that a contact point located in a contact area of the driving circuit board 20 is electrically contacted with the display panel 10 after piercing the ACF. Because the supporting part 13 between the display panel 10 and the driving circuit board 20 supports the blank area of the driving circuit board 20, when the driving circuit board 20 is pressed on the display panel 10, the gap between the driving circuit board 20 and the display panel 10 is filled with the supporting part 13, so that the deformation and local warping of the driving circuit board 20 can be effectively inhibited, therefore, the contact on the driving circuit board 20 can be more fully electrically contacted with the display panel 10, and the connection reliability is enhanced.

As an example, the supporting members 13 are uniformly distributed in the blank area of the driving circuit board 20, and may be, for example, equally spaced. The supporting parts 13 which are uniformly arranged support the blank area together, when the driving circuit board 20 is pressed on the display panel 10, gaps between the driving circuit board 20 and the display panel 10 are uniformly filled by the supporting parts 13, the supporting force for each position of the blank area is more uniform, and the deformation of the blank area of the driving circuit board 20 can be more effectively inhibited.

In some embodiments, the contactless position may also be located in an uneven area of the driving circuit board 20 where the contact distribution is not uniform.

The contacts on the driving circuit board 20 are unevenly distributed, and the intervals between the contacts are different, so that an uneven area is formed, and in the uneven area, the contact position and the non-contact position are provided. By providing the support member 13 at the non-contact position in the uneven region or by providing the support member 13 on the back surface of the display panel 10 so as to face the non-contact position in the uneven region, the support member 13 and the contact point support the uneven region together, and thus deformation of the driving circuit board 20 can be effectively suppressed and contact stability of the contact point with the display panel can be improved.

As an example, the positions corresponding to the contacts and the positions corresponding to the support members 13 are uniformly distributed in the uneven area of the driving circuit board 20.

The driver circuit board 20 has a contact position and a non-contact position in an uneven area, wherein the contact position corresponds to a contact position on the driver circuit board 20. The corresponding position of the supporting member 13 is a contactless position of the driving circuit board 20. The contacts and the supporting parts 13 in the uneven area of the driving circuit board 20 are uniformly distributed as a whole, and when the driving circuit board 20 is pressed on the display panel 10, the uniformly distributed supporting parts 13 and the contacts support the driving circuit board 20 together, so that the deformation of the uneven area of the driving circuit board 20 can be effectively inhibited, and the contact stability of the contacts and the display panel is improved.

In some embodiments, the contactless position is located in a low density region of the driving circuit board 20 where the contact distribution density is lower than the preset distribution density.

When the contacts on the driving circuit board 20 are sparsely distributed, the distance between the contacts is large, the contacts with the large distance form a low density region, and the low density region has a contact position and a non-contact position. When the driving circuit board 20 is press-fitted to the display panel 10, the positions between the sparse contacts, i.e., the non-contact positions, are deformed, resulting in poor contact between the contacts and the display panel. The supporting part 13 is arranged at a non-contact position in the low-density area on the driving circuit board 20, and the supporting part 13 and the contact jointly support the low-density area on the driving circuit board 20, so that the deformation of the low-density area can be effectively inhibited, and the contact stability of the contact and the display panel is improved.

In one example, in the low-density area of the driving circuit board 20, the positions corresponding to the contacts and the positions corresponding to the supporting parts 13 are uniformly distributed, and the distribution density is greater than or equal to the preset distribution density.

In the low density region of the driving circuit board 20, there are a contact position and a contactless position, wherein the contact position corresponds to a contact position on the driving circuit board 20. The corresponding position of the supporting member 13 is a contactless position of the driving circuit board 20. The contacts and the supporting parts 13 in the low-density area of the driving circuit board 20 are uniformly distributed as a whole, and when the driving circuit board 20 is pressed on the display panel 10, the uniformly distributed supporting parts 13 and the contacts support the driving circuit board 20 together, so that the deformation of the low-density area of the driving circuit board 20 can be effectively inhibited, and the contact stability of the contacts and the display panel is improved.

The contactless position may be located in any one or more of a blank region, an uneven region, and a low-density region, that is, the supporting member 13 may correspond to any one or more of a blank region, an uneven region, and a low-density region.

In some embodiments, the support member 13 is disposed on the back of the display panel 10 and corresponds to at least a portion of the contactless position. The back surface of the display panel 10 is the surface opposite to the display surface of the display panel 10. For example, the support member 13 corresponds to a blank area position of the driving circuit board 20. The supporting member 13 may be fixed at a corresponding position of the display panel 10 (e.g., a non-display area of the display panel 10), and then the driving circuit board 20 is pressed onto the display panel 10, the contacts on the driving circuit board 20 are electrically connected to the display panel 10, and the blank area on the driving circuit board 20 is supported by the supporting member 13, so that the blank area is effectively supported, the local warpage of the driving circuit board 20 is suppressed, the contacts on the driving circuit board 20 can be more fully electrically contacted with the display panel 10, and the connection reliability is enhanced. Fixing the supporting member 13 on the back surface of the display panel 10 facilitates fixing the supporting member 13 to the display panel 10 and improves the production efficiency since there is no interference of other devices on the display panel 10.

In other embodiments, the supporting member 13 is disposed at a non-contact position on the driving circuit board 20. Such as blank areas on the driver circuit board 20. The supporting member 13 can be fixed on the blank area of the driving circuit board 20, then the driving circuit board 20 is pressed on the display panel 10, the contact on the driving circuit board 20 is electrically connected with the display panel 10 in a contact manner, the supporting member 13 on the blank area of the driving circuit board 20 is abutted against the display panel 10, the blank area of the driving circuit board 20 is effectively supported, the local warping phenomenon of the driving circuit board 20 is inhibited, the contact on the driving circuit board 20 can be more fully electrically contacted with the display panel 10, and the connection reliability is enhanced. Compared with the method that the supporting parts 13 are arranged at the positions of the display panel 10 corresponding to the blank areas, the supporting parts 13 are arranged at the blank areas on the driving circuit board 20, so that the positions needing to be supported can be intuitively and accurately determined without measuring and calculating according to the blank areas, and the supporting reliability is ensured.

The display panel of the embodiment of the present disclosure is not limited to the support member 13 provided on the back surface of the display panel 10 or the blank area of the driving circuit board 20. In other embodiments, the support member 13 may be disposed at a position corresponding to the blank region on the rear surface of the display panel 10, and the support member 13 may be disposed in the blank region of the driving circuit board 20 to support the blank region by the two support members 13.

"and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. The singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It will be further understood that the terms "first," "second," and the like are used to describe various information and that such information should not be limited by these terms. These terms are only used to distinguish one type of information from another and do not denote a particular order or importance. Indeed, the terms "first," "second," and the like are fully interchangeable. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present invention.

It will be further understood that the terms "central," "longitudinal," "lateral," "front," "rear," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing the present embodiment and to simplify the description, but do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation.

It will be further understood that, unless otherwise specified, "connected" includes direct connections between the two without the presence of other elements, as well as indirect connections between the two with the presence of other elements.

It is further to be understood that while operations are depicted in the drawings in a particular order, this is not to be understood as requiring that such operations be performed in the particular order shown or in serial order, or that all illustrated operations be performed, to achieve desirable results. In certain environments, multitasking and parallel processing may be advantageous.
