Problems solved by technology

[0010] The technical problem to be solved by the present invention is to provide a color filter, which can effectively reduce the leakage current and short circuit of the black matrix caused by the current tunneling effect. At least one isolated channel, so as to avoid the abnormal light emission of the color photoresist caused by the working current passing through the black matrix

Embodiment Construction

[0073] First, see Figure 2A and Figure 2B , are respectively a top view and a schematic cross-sectional view of a preferred embodiment of the present invention; There is at least one black matrix 33 (Black Matrix), and a plurality of color photoresists 35 are added on the light-transmitting substrate 31 without the black matrix 33, wherein the black matrix 33 not covered with the color photoresist 35 is chiseled An isolation channel 34 is provided. Moreover, a protection layer 37 (over coat) is covered above the black matrix 33, the isolation channel 34 and the color photoresist 35, and a first dielectric layer 39 is arranged on the top of the protection layer 37, and through the protection layer 37 and the first dielectric layer The setting of 39 can prevent the operating current from passing through the black matrix 33 due to the tunneling effect and affecting the light emitting situation of the adjacent color photoresist 35 .

Abstract

The present invention relates to a color filter capable of preventing production of current tunneling effect. It is characterized by that its main structure includes a transmission base plate; a black matrix placed on particle upper surface of said black matrix; several color light barries which are fixedly placed on the transmission base plate surface on which the black material is not placed and at least an isolating channel is cut on the black matrix which is not covered with said color light barrier; and a protective layer for covering the periphery of said black materix and said color light barrier.

Description

technical field [0001] The invention relates to a color filter, in particular to a color filter capable of avoiding current tunneling effect. Through the setting of isolation channels, the purpose of improving the definition of the light-emitting area of ​​the color filter can be achieved. Background technique [0002] With the vigorous development of the optoelectronic industry, people enjoy the convenience brought by technology. However, how to manufacture high-quality and low-cost flat-panel displays has always been a goal that major manufacturers are striving to achieve. Compared with other display structures, organic electroluminescence display (OLED) has the advantages of self-illumination, high brightness, wide viewing angle, low power consumption, high response speed, light and thin panel, simple component structure and manufacturing process, etc. Therefore, it has attracted the attention of research institutes and manufacturers in various countries. [0003] For v...
