Abstract

A grid display device and a grid display method in a mobile terminal are provided. The grid display device in a mobile terminal includes a scroll control unit that displays a grid to be displayed on a screen of a display unit of the mobile terminal using a scroll bar when the grid is larger than the screen and a grid display unit that displays meshes of the grid on the screen and changes contents to be displayed in the fixed mesh of the grid in correspondence with a changed position of the scroll bar. According to the grid display device in a mobile terminal, it is possible to control a display of a grid so that the grid used in the mobile terminal having relatively low performance can rapidly operate.

Claims

1. A grid display device in a mobile terminal comprising:

a scroll control unit that displays a grid to be displayed on a screen of a display unit of the mobile terminal using a scroll bar when the grid is larger than the screen; and

a grid display unit that displays meshes of the grid on the screen and changes contents to be displayed in the mesh of the grid fixed to a specific position in correspondence with a changed position of the scroll bar,

wherein the grid display unit includes

a mesh display unit that displays the meshes of the grid having the same interval on the screen of the display unit,

a content display unit that displays contents to be described in the meshes on the screen, and

a mesh content changing unit that maintains the meshes in a state where the meshes are not newly rendered and changes only the contents to be displayed in the meshes when the scroll bar moves, and

wherein the mesh content changing unit changes a color of the meshes maintained in the state where the meshes are not newly rendered and a selected area in correspondence with the position specified by the scroll bar when the scroll bar moves.

2. The grid display device in a mobile terminal according to claim 1, further comprising a specific area rendering unit that renders only the displayed contents of the grid corresponding to the position of the scroll bar when the grid to be displayed on the screen of the display unit is larger than the screen.

3. The grid display device in a mobile terminal according to claim 2, further comprising a set image processing unit that further renders corresponding areas of the contents to be described in the meshes specified in advance depending on a velocity or an acceleration of the scroll bar manipulated by a user.

4. The grid display device in a mobile terminal according to claim 3, wherein a non-imaged area of the contents corresponding to the moving state of the scroll bar is maintained in a non-imaged state.

5. The grid display device in a mobile terminal according to claim 2, wherein the specific area rendering unit renders contents specified by the position of the scroll bar and contents of a previous page or a subsequent page to be displayed depending on the movement of the scroll bar when the grid to be displayed on the screen of the display unit is larger than the screen.

6. The grid display device in a mobile terminal according to claim 1, wherein the grid display unit further includes an image creating unit that creates meshes of the grid and contents to be displayed in the meshes of the grid as an image.

7. The grid display device in a mobile terminal according to claim 6, wherein the grid display unit further includes a function activating unit that dynamically creates components included in the contents created as an image and activates the functions of the components when a user clicks the components.

8. The grid display device in a mobile terminal according to claim 6, wherein the image creating unit is a canvas tag.

9. The grid display device in a mobile terminal according to claim 1, further comprising:

a basic FPS setting unit that sets a basic FPS (frame per second) at which the screen is to move depending on an OS of the mobile terminal;

a maximum FPS measuring unit that measures a current maximum FPS of the mobile terminal;

an FPS comparing unit that compares the basic FPS with the maximum FPS; and

a use FPS setting unit that sets the smaller FPS of the basic FPS and the maximum FPS as an FPS to be used.

10. A grid display method in a mobile terminal comprising the steps of:

displaying a grid to be displayed on a screen of a display unit of the mobile terminal using a scroll bar when the grid is larger than the screen; and

displaying meshes of the grid on the screen and changing contents to be displayed in the mesh of the grid fixed to a specific position in correspondence with a changed position of the scroll bar,

wherein the step of changing the contents to be displayed includes the steps of

displaying the meshes of the grid having the same interval on the screen of the display unit,

displaying contents to be described in the meshes on the screen, and

maintaining the meshes in a state where the meshes are not newly rendered and changing only the contents to be displayed in the meshes when the scroll bar moves, and

wherein a color of the meshes and a selected area are changed in correspondence with the position specified by the scroll bar.

11. The grid display method in a mobile terminal according to claim 10, further comprising a step of rendering only the displayed contents of the grid corresponding to the position of the scroll bar when the grid to be displayed on the screen of the display unit is larger than the screen.

12. The grid display method in a mobile terminal according to claim 11, further comprising a step of further rendering corresponding areas of the contents to be described in the meshes specified in advance depending on a velocity or an acceleration of the scroll bar manipulated by a user.

13. The grid display method in a mobile terminal according to claim 12, wherein a non-imaged area of the contents corresponding to the moving state of the scroll bar is maintained in a non-imaged state.

14. The grid display method in a mobile terminal according to claim 11, wherein contents specified by the position of the scroll bar and contents of a previous page or a subsequent page to be displayed depending on the movement of the scroll bar are rendered when the grid to be displayed on the screen of the display unit is larger than the screen.

15. The grid display method in a mobile terminal according to claim 10, wherein the step of changing the contents to be displayed further includes a step of creating meshes of the grid and contents to be displayed in the meshes of the grid as an image.

16. The grid display method in a mobile terminal according to claim 15, wherein the step of changing the contents to be displayed further includes a step of dynamically creating components included in the contents created as an image and activating the functions of the components when a user clicks the components.

17. The grid display method in a mobile terminal according to claim 15, wherein the image is an image created by a canvas tag.

18. The grid display method in a mobile terminal according to claim 10, further comprising:

a step of setting a basic FPS (frame per second) at which the screen is to move depending on an OS of the mobile terminal;

a step of measuring a current maximum FPS of the mobile terminal;

a step of comparing the basic FPS with the maximum FPS; and

a step of setting the smaller FPS of the basic FPS and the maximum FPS as an FPS to be used.
