Since the finger does not need to move during operation, the position is fixed when the button is clicked, and clicking is easy. When in operation, the fingers do not need to leave the machine body, and the operation and the dragging operation of the pointer which need to be moved greatly become extremely simple. The pointer is not moved by only lightly touching the pointer, so that misoperation cannot occur. Track Point is simply a simple matter of coating a ceramic pointing stick with a rough rubber cap in appearance. In fact, its interior is coagulated with various elaborate designs, very ergonomically friendly. When the pointing stick is lightly pushed by a fingertip, the ceramic plate at the bottom of the pointing stick can generate slight bending, and 4 bending sensors arranged on the ceramic plate can immediately sense the direction and the magnitude of the force. Track Point is well operable in that it can quickly sense even very small forces exerted on the Track Point and can accurately perform operations depending on its intensity and duration. If only a slight force is applied, the pointer will move only a few units of dots. The pointer is accelerated to move smoothly by continuing to push. If a large force is applied instantaneously, the pointer moves quickly to the target. The ingenious design makes the pointer move to really fit the operation intention of the user.

The Track Point is convenient for a human finger to accurately press and ensures that a nearby keyboard cannot be influenced, so that the Track Point protrudes out of the keyboard by a certain distance and is relatively close to the liquid crystal screen, the Track Point is between the keyboard and the liquid crystal screen when the pen electronic product is in a closed state, the pen electronic product has a vibration phenomenon in the use or reliability test process, and the liquid crystal screen and the operating rod are continuously impacted and extruded.

In this embodiment, the display device in the present invention is a liquid crystal notebook computer, and in other preferred embodiments of the present invention, the display device may also be other mobile terminal devices.

As shown in fig. 1 and 2, fig. 1 is a schematic view of a display device in an embodiment, and fig. 2 is a side view of the display device in the embodiment in a closed state. The display device in this embodiment includes a first member 100, a second member 200, and a connecting member 300.

The second member 200 is rotatably connected to the first member 100, specifically, one end surface of the second member 200 and one end surface of the first member 100 are respectively connected to the connecting member 300, the second member 200 and the first member 100 can rotate about the central axis of the connecting member 300, the included angle between the second member 200 and the first member 100 is 0-160 °, and when the included angle between the second member 200 and the first member 100 is 0 °, the top surface of the first member 100 and the top surface of the second member 200 are oppositely disposed.

The first part 100 includes a keyboard 110, the keyboard 110 is disposed at an upper middle position of the first part 100 to implement data input, and specifically, the keyboard 110 includes a keyboard body 111, keys 112 and protrusions 113. The keyboard body 111 is provided with a plurality of keys, the keys 112 are correspondingly arranged on the keys, and each key 112 can move up and down perpendicular to the keyboard body 111, so that a user can realize data input by pressing the corresponding key 112.

The second component 200 includes a display panel 210, the display panel 210 is a liquid crystal display panel, and includes a display area 201 and a non-display area 202, wherein the display area 201 is disposed at a middle position of the display panel 210 for displaying a picture, and the non-display area 202 is disposed around the display area 201 for shielding non-display traces in the display panel 210.

In order to facilitate the use and carrying of the display device, the display device needs to have two states of opening and closing, that is, when the display device is used, the second part 200 and the first part 100 form an included angle between 80 ° and 150 °, so that when a user clicks the keyboard 110, the user can see the eyes on the display panel 210. Display device is during non-user state, need laminate display panel 210 and keyboard 110, and the contained angle between display panel 210 and the keyboard 110 is zero promptly, this moment display device is a more regular rectangle piece, portable transportation, and display panel 210 relatively soft display panel laminates with the button surface of keyboard 110 easy deposition mutually, effectively prevents external impurity invasion and hard thing striking, has effectively promoted display device's life.

Generally, a notebook computer or other mobile terminals need to be externally connected with a mouse to move and click a cursor, although a touch screen is disposed on a keyboard 110 in the existing notebook computer, and the cursor is moved by moving or clicking a finger on the touch screen by a user, in order to reduce the overall size of the notebook computer, the area of the touch screen is not too large, when the cursor needs to be moved greatly, it is very inconvenient to move the cursor on the touch screen by simply relying on the finger, and in order to solve this problem, a designer additionally adds a small red Point (Track Point) on the keyboard 110, where the small red Point is the protrusion 113 in this embodiment. The protrusion 113 is located at the middle position of the keyboard 110 and is disposed between the two keys 112, which is convenient for the user to operate.

As shown in fig. 4, protrusion 113 includes connecting rod 1131 and casing 1132, connecting rod 1131 is ceramic slender rod, one end is fixed on keyboard body 111, casing 1132 is the elasticity external member, the cover is established at the other end of connecting rod 1131, and the top of casing 1132 is rough surface, be used for increasing the frictional force of user's finger and casing 1132, prevent skidding, user's finger is as long as dabbing casing 1132, and nudge casing 1132, casing 1132 will drive connecting rod 1131 and rotate, connecting rod 1131 bottom is connected with the ceramic plate, when connecting rod 1131 rotates, the ceramic plate can take place the bending, install direction and the size of crooked sensor on the ceramic plate will be perception dynamics immediately, it can be fast the perception even very little strength of exerting on casing 1132, and can accurately realize the operation according to its intensity and duration. If only a slight force is applied, the pointer will move only a few units of dots. The pointer is accelerated to move smoothly by continuing to push. If a large force is applied instantaneously, the pointer moves quickly to the target. The ingenious design makes the pointer move to really fit the operation intention of the user.

However, since the protrusions 113 are disposed between the keys 112, in order to ensure that the protrusions 113 can sense the strength and direction of the user's fingers, the height G2 of the protrusions from the keyboard body 111 needs to be higher than the height G1 of the protrusions from the keys 112 to the keyboard body 111, and the difference between the heights of the keyboard body 111 and the keys 112 is G3-G2-G1, where G3 is a number greater than zero.

In the manufacturing process of the display device, in order to reduce the volume of the display device in the closed state as much as possible, the display panel 210 and the keyboard 110 are generally attached seamlessly, that is, in the closed state, the display surface of the display panel 210 is tangent to the keys 112 of the keyboard 110, and since the height of the protrusion 113 is higher than the height of the keys 112, when the display device is closed, a pressing force is generated between the protrusion 113 and the display panel 110, so that the display surface of the display panel 210 is damaged, the display panel 210 is broken, scratched or dented, and the sensitivity of the protrusion 113 is reduced.

Since the display panel 210 in this embodiment is a liquid crystal display panel, the main principle is that the brightness of the picture is realized by the deflection of the liquid crystal, and due to the flowing performance of the liquid crystal, a spacer is generally disposed in the display panel 210, and the spacer is used to support the upper and lower substrates of the display panel 210, so as to ensure that the cell thicknesses of the regions of the display panel 210 are equal, and the hardness of the spacer is high. When the display device is closed, the protrusion 113 impacts the display area 201, the two sides of the glass substrate of the display area 201 are respectively provided with the spacing columns and the protrusion 113 with higher hardness, and the buffer is smaller in the impact process, so that the glass substrate is easily damaged. In this embodiment, the density of the spacers on the display panel 210 corresponding to the protrusions 113 is reduced, so that the glass substrate between the spacers is more easily deformed, a better buffering effect is achieved, and the risk of damage to the glass substrate is reduced.

Specifically, in this embodiment, the display panel 210 further includes a first region 2101, a second region 2102, a first substrate 211, a first spacer 212, and a second spacer 213, where the first region 2101 corresponds to a position of the protrusion 113 in the closed state of the display device, the second region 2102 surrounds the first region 2101, and is a display region 201 together with the first region 2101, the first spacer 212 is uniformly disposed in the display region 201 of the display panel 210, and the second spacer 213 is disposed in the second region 2102 of the display panel 210, and since the density of the spacers in the first region 2101 is smaller than the density of the spacers in the second region 2102, when the display device is closed, the probability that the protrusion 113 directly impacts the spacers through the glass substrate is reduced.

In order to ensure uniform cell thickness of the display panel 210 and to limit the flow of liquid crystal in the display panel 210, in the embodiment, the projection 113 has an orthographic projection area of the first region 2101, the area of the first region 2101 is 20% to 50%, and the ratio of the area of the first region 2101 to the area of the second region 2102 is less than 0.01.

As shown in fig. 3, in order to further reduce the probability that the protrusion 113 hits the spacer, in this embodiment, the second spacer 213 is a main spacer and plays a role of main support, the first spacer 212 is an auxiliary spacer and plays a role of secondary support and liquid crystal flow prevention, the length of the first spacer 212 is H1, the length of the second spacer 213 is H2, the difference between the lengths of the two spacers is H3 — H2 — H1, and H3 is a number greater than zero. When the display device is in a closed state, the area corresponding to the protrusion 113 is only provided with the first spacing column 212, the first spacing column 13 and the key 112 have a gap, the gap is larger than the part of the protrusion 113, which is higher than the key 112, i.e. H3-G3>0, so that even if the protrusion 113 is opposite to the first spacing column 212 when the display device is in the closed state, the protrusion will not impact the first spacing column 212 due to the gap, the technical problem that the glass substrate between the spacing column and the protrusion 113 in the display panel 210 is broken, scratched or dented is prevented, and the sensitivity of the protrusion 113 is also prevented from being reduced.

The beneficial effects of this embodiment lie in, display device in this embodiment sets up the arch in keyboard middle part position, through pressing the protruding purpose that reaches the mobile cursor that promotes, with the interval post density reduction in the display panel second region, when display device closed, reduce the protruding probability of striking display panel interval post, prevent that display panel from appearing broken piece, mar or sunken technical problem, also prevent that bellied sensitivity from reducing, promoted display device's life.
