Embodiment 1

[0024] An embodiment of the present invention provides a touch panel. The touch panel includes a first substrate, and a color filter layer, a plurality of touch sensing electrodes, and a plurality of touch driving electrodes are arranged on the first substrate; a color pixel unit; the touch sensing electrode is arranged between adjacent color pixel units, and has a light-shielding function; the touch driving electrode, which is insulated from the touch sensing electrode and arranged crosswise, is applied with touch scanning during the touch stage signal, the common electrode signal is applied during the display phase.

[0025] Embodiment 1 of the present invention takes the color filter substrate with the color filter layer as the first substrate as an example to describe the touch panel provided by the embodiment of the present invention in detail. The color filter substrate includes a substrate 1, a touch sensing electrode 2, a color filter layer 3 and touch drive electrodes...

Embodiment 2

[0032] Embodiment 2 of the present invention will describe the touch panel in Embodiment 1 in detail in combination with practical applications, but of course it is not limited thereto.

[0033] Such as figure 2 As shown, in order to realize the touch function in the embodiment of the present invention, the touch sensing electrodes 2 and the touch driving electrodes 4 are insulated from each other and intersected. Shading strips 5 can also be provided. If the touch sensing electrodes 2 are arranged between the color pixel units in adjacent columns, the light shielding strips 5 and the touch sensing electrodes 2 are intersected and arranged between the color pixel units in adjacent rows. If the touch sensing electrode 2 is arranged between the color pixel units of adjacent rows, the light-shielding strip 5 and the touch sensing electrode 2 are intersected and arranged between the color pixel units of adjacent columns to better of shading.

[0034] Preferably, the light-shiel...

Embodiment 3

[0040] The embodiment of the present invention is described by taking a transflective display panel as an example, and it is not limited thereto. The color filter substrate in the transflective display panel provided by the embodiment of the present invention has the same structure as that of Embodiment 1 and Embodiment 2, and the embodiment of the present invention will only describe the differences.

[0041] The touch panel provided by the embodiment of the present invention further includes a second substrate opposite to the first substrate. The second substrate in this embodiment may specifically be an array substrate. The schematic diagram of the array substrate is as follows Figure 8 shown. A number of pixel display units arranged in matrix are formed on the second substrate in the same arrangement as the color pixel units arranged in matrix on the first substrate, and a reflective area and a transmissive area are arranged in each pixel display unit to form In the tran...

Abstract

A touch panel and a display device. The touch panel comprises: a first substrate, wherein a colour film layer is arranged on the first substrate. The colour film layer comprises a plurality of colour pixel units arranged in the form of a matrix. The first substrate further comprises a plurality of touch-control inductive electrodes and a plurality of touch-control drive electrodes, wherein the touch-control inductive electrodes are arranged between adjacent lines or adjacent rows of colour pixel units and have a light-shading function; and the touch-control drive electrodes and the touch-control inductive electrodes are insulated from each other and are arranged crosswise, touch-control scanning signals are applied to the touch-control drive electrodes at a touch-control stage, while common electrode signals are applied to same at a display stage. The touch panel simplifies the structure and the manufacturing process of an embedded touchscreen.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a touch panel and a display device. Background technique [0002] As a new human-computer interaction device, the touch screen has attracted more and more attention from users and developers. Most of the existing touch screens use capacitive touch screens. Capacitive touch screens can be divided into built-in touch screens and external touch screens. Among them, the plug-in touch screen is produced separately from the touch screen and the LCD display, and then bonded together to form a touch-enabled LCD display. The plug-in touch screen has high production costs, low light transmittance, and thick modules. shortcoming. The embedded touch screen embeds the touch electrodes of the touch screen inside the liquid crystal display, which can reduce the overall thickness of the module and greatly reduce the production cost of the touch screen, and is favored by major panel manufact...
